He has shown to be lazy in "A Lemony Lesson" where he told Paper they didn't need to compete. He has the ability to cut into things due to his sharp physical nature. However, he was shown to have a soft side in spite of being so traitorous and mean, as he likes the television show Desperate Housewives and Dora Dolls.

He lives on Cold Island. He’s very moody and sarcastic, but also sad. He doesn’t show it much, but he’s VERY overprotective. He loves hugs but he doesn’t want to give any because he’s afraid of making others cold. He’ll often lead people around the island to warmer places. He has a very short temper and isn’t afraid to yell at anyone who harms those smaller than them. It’s a very rare to see him smile. He’s always very serious. He’s one of the bigger monster on Cold Island.

Moody, Sad

He lives on Air Island. He’s always busy helping his friends, so he usually has to walk and talk if he ever socializes with anyone. He’s bigger than most monsters and likes to pick up his friends and carry them around the island. Despite him being very energetic and hyper, he’s always working and tires himself out, so occasionally he needs to take a nap. He absolutely loves cuddles or even just hugs.

Hyper, Friendly

He is dedicated to good showmanship and raising the stakes of the game, often in favor of producing the most exciting competition possible. This often means the contestants get the short end of the stick, as MePhone4 comes up with challenges that range from mundane to relatively normal to disgusting to extremely dangerous.

He lives on Bone Island. Dapper Clackula doesn't have a mouth of its own with which to chitter-chatter about its many cultured interests, so the Bone Elemental leaves all the yammering to its loquacious little hands. If only they'd behave! When the lanky gentle-Mon's appendages get too snippy with dinner guests, it delivers the quickest of pin-point pinches to each chatterbox with its dainty fangs. While not enough to cause any pain, it's certainly enough to send a message: keep it classy!
