Mucoid

"Those eggs hurt! I'm off for a rest while the mucoids soften you up!"

- Terry

Mucoids are Terry's "snotty buddies" that he spits out at Banjo and Kazooie to help take them down as he goes and rests during the boss battle with him in Terrydactyland.

Use the Forward Roll or Dragon Kazooie's Fire Breath to easily dispatch of these disgusting creatures. Destroy them quickly or else they could surround you.
