|Debut||Fish Out of Water|
|Voiced by||Brian Drummond|
Lemasque is a raccoon with a French accent who lives in Downtown City's storm drain. He's formed a group with an opossum, three rats and two mice.
When Russell took the pets to the storm drain to rescue Goldy, despite Sunil's reluctance, Penny Ling was displeased with the amount of garbage, and Pepper commented about the darkness. After Vinnie remarked that no one could survive there for very long, Lemasque showed up and told them otherwise.
He showed them with a song how he and his gang enjoy the place even if it's dirty. They like the smell and make use of all the garbage, recycling it into things they can use, including the clothes they wear.
