Toxi-Gag

Toxi-Gags are poisonous green gas bubbles that appear out of Toxi-Klangs in Grunty Industries. When Banjo and/or Kazooie enter its "patrol area", it whisks itself over to them and covers their face, forcing them to hold their breath. Kazooie is fast enough to outrun them, but Banjo can't avoid them unless he goes out of his way. Toxi-Gags can only be destroyed with the Wonderwing or by being frozen and attacked.
