Yumbly

Yumblies are small, red, fruit-like creatures found in Bubblegloop Swamp in Banjo-Kazooie. They appear in Mr. Vile's game, where Crocodile Banjo needs to eat more Yumblies and/or Grumblies than him.

Once the challenge is beaten, Mr. Vile can be interacted with to play a game where Crocodile Banjo needs to eat 35 Yumblies to obtain an Extra Life.
