Marshmallow Hamster is an S-grade Pet in LINE and an Epic Pet in OvenBreak. When its ability activates, it will act like a Magnet Jelly absorbing all jellies ahead of it, except for Dark Moon Jellies in the City of Wizards in LINE. Its cheeks eventually grow larger until, when it's nice and full, it will burp out an Energy potion (along with a bunch of Cocoa Marshmallow Jellies) that you can collect for extra Energy and points.
(LINE)Its eyes are painted with super concentrated drops of cocoa and its bright red nose with a dash of cherry syrup. He looked to be thin and looked like deflated marshmallow when he was bullied by his friends, but ever since he met the Cocoa Cookie, he's been happier than ever and now he can melt anyone's heart when he smiles with his plum cheeks stuffed with sunflower seeds.
(OvenBreak) While painting the face with chocolate on a roasted marshmallow, a drop of cherry syrup fell down and became its nose. And if you ever saw it you would even say it glows. All of the other marshmallows, used to laugh and call it names. But ever since it met Cocoa Cookie, it's been happier than ever, filling its plum cheeks with delicious Jellies.
