Chicago the Lion
From Muppet Wiki
Chicago the Lion is a vegetarian lion, who appeared on Sesame Street beginning in 1990. Although he was dropped as a major character in 1997, he still popped up occasionally from Season 33 onward.
In episode 3161, fish explorer Wanda Cousteau dresses up as broccoli in order to hide from the fish-hungry Wolfgang the Seal. Fooled by Wanda's costume, Chicago chases Wanda.
Chicago was also seen at the end of a Play With Me Sesame skit in which Super Grover comes in to save the day at the wrong time, mistaking the pretend noises the viewer makes for the real thing.
