When in level 3, go in the right subway entrance to find one of the arcade games.
Hint: Defeating leader Foosa
When you are facing the leader Foosa at the very end when you are on a platform with spikes around you, he will first make the back catch on fire then start chasing you. He will get tired and give you a chance to hit him. After that, he will blow green air at you. Keep jumping. He will then go to the other side of the platform and start to give the vultures a signal to attack. Keep roaring at them. This process will repeat until the leader Foosa's life meter goes out. Sometimes the penguins will drop mangos.
Hint: Easy coins
In level 3 as Gloria (the hippo), hit thirty cars to get 15 coins. Note: this only works once. Get 30 coins, then go to the Zoovenir Shop. Buy the Coin Magnet, which will make nearby coins come to you. After completing the game, you can go back and get all the coins that were in the water that you could not get before.
Hint: Marty's Escape: Rocket mini-game
Play level 2, "Marty's Escape", as Marty (the zebra). Follow the penguin until he crawls into a hole. You will see two hay bales at this point. Kick the hay bales to reveal a shack which contains an arcade-type mini-game.
When taking on the police you can use the statues, manholes, cages, and carts.
Hint: Return To The Beach: Defeating the crocs
Play as Marty and wait until the first two crocs stop spinning and are out of breath. Then, kick them. For the leader croc, wait until he is done with his fighting moves. He will be out of breath. Then, kick him.
Hint: The Banquet
Go to the main lemur that is on the drum where all the food lies. Talk to him ten times in a row to earn food. Note: This can only be done two times.
