    First off, they said nothing about Mettaton EX's quiz. If you type in Toby Fo, a swear, legs, leave it blank, or etc. Mettaton gives responces. Second, if you keep petting lesser dog his neck stretches along the whole screen. Third, if you kill anything in the pacifist route, it doesnt change to genocide, but you have to fight sans. Next, it doesnt explain the names well. If you type in Metta you get the rwspone OH!!! ARE YOU PROMOTING MY BRAND??!? Also if you tpe in frisk fo pacifist it warns you.

  2. guest-avatar

    There weren't a lot of good secrets. Also, there were some grammar mistakes and the San's room trick didn't work for me, and write something about Gaster. Please add more secrets and take out the constant ads for me to give it five stars.

  3. guest-avatar

    The game wouldn't let me scroll down after a point even though there was more to read, and doesn't have much content. Pretty okay other than that.

  4. guest-avatar

    It just needs a bit more perhaps more about Gaster or more hidden rooms like if you find the four hidden flowers in the bridge thing. Other than that pretty good : )

  5. guest-avatar

    one word response on first look: NYEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEH btw add gaster's room, the part when you get in sans and papyrus' house, if u walk between the kitchen and the living room quickly over and over, papyrus will say something different, the "pet lesser dog too much and his neck will grow", translate entry number 17 in hotland, it's in wingding and there is a translation for wingding, seriously just search up on youtube "top ten facts about undertale" and boom, about ten more facts for you

  6. guest-avatar

    I clicked open app and it showed me name serious mode fighting flowey. And there is no button to start. Playing?

    I found more secrets such as the gaster people and hard mode it could kid have more content but it's pretty good. Also you didn't mention that you had to walk right in sans' room. And by the way it's been 2 years so it actually is legal( to that random person who said have fun in prison )

  8. guest-avatar

    The sad fact this is the only undertale thing on the play store so if u make something better like some live undertale wallpapers you would be brilliant.

  9. guest-avatar

    Its Yee Boy Liam!


    I'm kinda good but there's WAY MORE SECRETS​!! like:1 kill toriel then go back to were you start then you see toriel beside flowers when you talk to here she said the same as asriel when you compleat the game and go back.

    You need to kill and spare enemies not just go kill everyone or help everyone.

    There are just a fraction of secrets here. Tell us about the genocide run if you spare a certain monster. Or the no mercy crerpypasta. Or the audio clip ABC123

  12. guest-avatar

    This game gave up on me it stopped as soon as I opened it I hava a samsunggalxy 3tablet and if u have one 2 dont download this app ok?

  13. guest-avatar

    mettaton. exe has stopped working


    Omg I did not know you could do that in a neutral route when you see sans. 😛😮😮😮😮(BTW I haven't even finished my pacifist route and still whacthed spoilers. That was dumb. 😛)

  14. guest-avatar

    Some wrong grammar and spelling here and there. Needs A LOT more stuff added.

  15. guest-avatar

    It doesn't give you many secrets

  16. guest-avatar

    You need to put w.d gaster genocide run and secret rooms but i like the app thanks

  17. guest-avatar

    You show in the picture undertale secrets san's secret yes in his workshop you will see a broken time machine a badge a photo and a blueprint actually if you know earthbound in the picture it says that sans is in the picture with three human he looks happy actually the one boy in earthbound was sans is the boy that wears a cap if you can identify sans bone hands are the same at the boy at the earthbound cause the boy in earthbound is also hiding his hand so sans is the boy on earthbound(sorry I don't know the name of the boy but you can search it in Google);) but there'should more you need to know about sans from know this is my explanation I hope it helps you in playing undertale

  18. guest-avatar

    I'm not that far into the game, but these secrets help me a lot! Just one question, why can't we scroll any farther than the Serious Mode secret?

  19. guest-avatar

    No more adds love the secrets to and won't let me scroll down

  20. guest-avatar

    I liked it but when I got to serious mode i couldn't scroll down D;

  21. guest-avatar

    Read the whole thing and didn't find the W.D gaster secret.

    If it was updated with more secrets, it would be worth keeping. It only has about 7, so it's not worth the phone space. You're better off Googling what you want to know.

  23. guest-avatar

    The facts are fine, but there're only very few facts to read.

  24. guest-avatar

    Could you add in the squeaky mushroom door

  25. guest-avatar

  30. guest-avatar

    It just needs more secrets and stuff! I like the app though.

    Elisabeth Garcia

  41. guest-avatar


  42. guest-avatar

    I love it because now I know the secret

  43. guest-avatar

    It dosnt even have the More popular ones!!!!

  44. guest-avatar

    This is a pretty good app, but after a while, it wouldn't let me scroll down anymore, and there was still an article there. I dunno if this has been fixed in the time I haven't had this downloaded, but it was like that the last time I had it. I don't mean to be rude, by the way.

  45. guest-avatar

    You can literally find more content about Undertale on the wikipedia page, this is worse than a high school essay... and the "secrets" are just things that most people who search for an Undertale app will know about. I'll not even bother explaining the amount of ads on this thing...

  46. guest-avatar

    I would give it 5 stars if there was more. Know I don't know if an update happened since I got rid of it but if there could be more added like gaster or the dog or any other thing from undertale added I would change it to 5

  47. guest-avatar

    It won't work right as I thought it would be great game but no

  48. guest-avatar

    This is a great app for people who doesnt know about some secrwts yet but sadly it lacks way in content.

  49. guest-avatar

    OK these secrets are good but it needs facts people don't know but are still true not something you found off of YouTube and I'm pretty sure we know more than that app

  50. guest-avatar

    It has litle to no good information aboit UNDERTAIL and its secrets. So ya u can fined more by playing it your self thin this app... HOI IM TEMMY IF U DONATE MONEYS TO SEND ME TO COLAGE AND DIES ALOT U CANS GET TEMMY ARMER IF U...... no temmy. Just farm dog silava lol :)

  51. guest-avatar

    Needs work.

  52. guest-avatar

    I rated 4 stars cause this seems to be the only undertale app in the store, so Ill credit you for this. I uninstalled it, though, because I knew all that anyway. (Oh, in some cases in the game, it changes names, like, undertale the musical, and floweytale)

  53. guest-avatar

    It's ok but if you added like the fun things like the hotdogs or the dog neck that stretches or how you end up in a garage after Papyrus beats you good app though

  54. guest-avatar

    It was interesting to read for about 5 minutes, then it was uninstalled again. There is almost no value to keep it. That content doesn't belong in an app.

  55. guest-avatar

    Daemion Johnson


    You forgot secret bosses like so sorry or where to find gaster or how to fight asriel dreemur

  56. guest-avatar
