This Mini-Game can be rather tricky at times. It can be found inside the crocodile in Bubblegloop Swamp. Banjo and Kazooie must transform into the Crocodile Transformation and enter the crocodile through one of the 2 holes in its nose. Inside, Mr. Vile will challenge them to his game.
There are 3 difficulty levels that must be beaten to acquire the prize. Each difficulty level has its own set of rules to follow.
Easy: The object of this difficulty level is to eat more red yumblies than Mr. Vile.
Medium: The object of this difficulty level is to eat more red yumblies than Mr. Vile, however Banjo and Kazooie must not eat the yellow grumblies that appear. Mr. Vile explains that the yellow grumblies aren't ripe, so Banjo and Kazooie shouldn't eat them. If Banjo and Kazooie does eat one they will become sick and unable to move for several precious seconds.
Hard: The object of this difficulty level is to eat what is shown at the top of the screen, either red yumblies or yellow grumblies. If Banjo and Kazooie eat what is not shown on the top of the screen, they will become sick and unable to move for several precious seconds.
Use the Control Stick to move the Crocodile and the B button to eat.
If Banjo and Kazooie successfully beat Mr. Vile in all 3 levels, he will reward them with a Jiggy.
