WARNING!! This game is highly addictive. I only had time to write this post today because I was out of lives on the game and was locked out for a short period of time.
You have to pop different colored groups of gumballs to feed the Dodo and advance to the next level. Each level has a new task such as popping 35 red, 35 yellow and 35 blue gumballs with a limited number of taps.
It is a game that you can play one level every now and then, or sit for hours playing (as my kids and I have done!).
