Chain Chomp (Elder Princess Shroob)

Shroob Chomps are enemies that appear in Mario & Luigi: Partners in Time. They are only used in an attack made by Elder Princess Shroob. It looks almost exactly like a normal Chain Chomp, but with a purple coloration and red Shroob eyes. When used, Elder Princess Shroob lets go of the Shroob Chomp and sends it at Mario, Luigi, Baby Mario and Baby Luigi. The Bros. have to jump repeatedly until a Bro. stomps on it or gets hit by it. It then drops out of the screen and out of sight.

Trivia
In Mario & Luigi: Bowser's Inside Story, Bowser Memory L's Bowser Memory Boo attack is very similar to the way a Shroob Chomp attacks.
