Remember Mr. Grumpy, the most hilarious marmot in the neighborhood? Well, guess what: he did not forget you at all, and he is not quite pleased to meet you again. Laugh at Mr. Grumpy's crankiness and play amazing pranks in this virtual pet game. You will also have to look after him and keep him well fed and clean. But… Who said it has to be easy on him?

Pay a visit to his house and interact with your, uh, "friend", in different funny environments! Customize Grumpy's style and annoy him putting funny hats, ties, glasses and clothes on him! Customize also Grumpy's house and make yourself comfortable! He will hate it!

• Bother Mr. Grumpy and get coins every time he is super nervous!
• Discover new tricks to see dozens of reactions from Mr. McGrump! Kids love it!
• Bathe him and put him to bed… And also wake him up very disturbingly!

Love the game


It is just so amazing that he has sooo many grumpy expressions! You know it’s just awesome well not even awesome but hilariously turdelbass (btw turdelbass means awesome isn’t ⭐️⭐️⭐️⭐️⭐️ awesome is ⭐️⭐️⭐️ and turdelbass is ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️) that you can make fun of grumpy with taking his picture and then adding a Couple of words to make it a hilarious thing. Now my favorite part is that his energy bar fills up so fast that I can play with him more and waste less time putting him to 😴. But my only complaints are that it only has 3 mini games and it says more soon but I can understand coding is a lot of work. Next lots of things are expensive and finally I wish that you could take him to other places then his house plus I wish that there is one that is a girl oh and MORE EXSERES

I love it 😍


My brother loves this game and including me cause is so fun it is so friendly and funny 😆. I love that the main character is a grump but please make more mini games if you can’t not think of any you can go see your other mini games of other apps that you made before like My boo . And please make other features so we can like it better. It is so fun for little kids and big kids . But please stop making to much ads like when I press on the sleep time button it would take me to an ad . I really like this game so I would give a 5 ⭐️ .

Oh no! An annoying bug!


This game is fun and makes for a good stress reliever because it is funny, but whenever I open the app to play it, and I connected it to Facebook, it now opens Facebook up in Safari and the Facebook app even though it says I've already authorized it, then when I go back to the grumpy app, it's frozen and I have to close and open it again! It still works but it is an annoying glitch and I hope you will fix it very soon! Or else I will be grumpy!
