Homing Chomp

Homing Chomps (also known as Silver Chomps) are a type of Chomp in Super Mario Galaxy 2. They resemble giant silver Chomps with yellow rings around their eyes, much like the Chain Chomp's design in Super Mario Sunshine, and red irises and pupils, which are constantly rolling around out of sync with each other. Unlike other Chomps, Homing Chomps always roll towards Mario or Luigi and try to hit him.

A single Homing Chomp first appears in the Rolling Masterpiece Galaxy at the end of the mission Silver Chomp Grudge Match. One later appears in the Slipsand Galaxy in the mission Sailing the Sandy Seas. Four Homing Chomps later appear in the Battle Belt Galaxy on the final planet in Mini-Planet Mega-Run and Mini-Planet Daredevil Run.

These enemies can be defeated only by Rainbow Mario, by pushing them off a cliff while on a Star Ball, or by the use of a rubbery bulb.

An extremely large Homing Chomp appears in the E3 2009 trailer of Super Mario Galaxy 2, though it never made it into the final game. In the trailer, it seems to be acting similarly to Sorbetti during the boss battle in the Freezy Flake Galaxy. Within the game's "ObjNameTable" file, there is a removed "WanwanSearchBig" entry, which is likely a remnant of this.
