Mr. Vile

Mr. Vile is a character found inside the giant crocodile shaped hut at Bubblegloop Swamp in Banjo-Kazooie. Fitting his name, he claims he is the meanest and greediest crocodile of them all. He challenges Banjo's crocodile transformation to try and eat more Yumblies than him. The prize after 3 rounds is a Jiggy, but all three rounds are slightly different.
 * The first round, you must eat more Yumblies than Mr. Vile.
 * The second round includes yellow Grumblies that will poison you.
 * The third round consists of the top of the screen saying which type to eat, the Yumblies or the Grumblies.

However,losing a round will cause Mr. Vile to try and chomp Banjo for 2 damage. For an easy, or less difficult, victory, use the Running Shoes. Once the Jiggy is earned, Mr. Vile offers a second challenge of playing three rounds for 3 extra lives at the cost of 1 life for a loss. He looks just like a Klaptrap from the Country series of Donkey Kong, which is fitting because both Donkey Kong and Banjo Kazooie were made by the same company, Rareware.
