An energetic breed of Zuum that went through a major redesign in the series. It originally looked like a pure Zuum with a bright yellow body and red spiderwebbed pattern on its back, much like the Dino breed called Mustard. When it reappeared in Monster Rancher 4, it was redesigned to look more like a Suezo, with all-yellow skin, a tail with a bob on the end, and a large round head with a single large eye. It later returned to its original appearance in Monster Rancher Advance.

Etymology Edit

Mustard is a condiment made from the seeds of a mustard plant, normally yellow in color.
