[IOS][2010s] Game where you ride on a cloud or something with party members and colorful little characters

There were like different locations or levels I think and you would ride on some cloud or floating thing to get to each level on the map. It had a 2D poptropica esque art style. I think one of the locations on the map was a cave you could go into. I vaguely remember there being some kind of grid formation where some colorful little guys would drop down on but I'm not sure if that was just for one character or the main game mechanic. Whether they were all filling up the screen or they would only stay on some parts of the screen is something I can't remember. It was probably some kind of tower defense or puzzle game or rpg?. You could also get new party members I think. I do remember though that it had some kind of microtransaction where you could buy some kind of currency or powerup because I had a jailbroken iPad 2 and advanced pretty far in the game I think by cheating.

I was a child playing this mid-early 2010s and the older I get the less I remember it so forgive me if its too broad
