Cheerup

One of the fanciest little monsters around, It's Mr. Cheerup, but you may call him Cheerup if that's preferable. 

In the past he's been known to work jobs serving sophisticated monsters, while there was never any complaints of his work, in fact many of them praised his hardworking attitude and professionalism, he never seemed to stick around. It wasn't until he met a particular Sir Berus, that for the first time he'd work more permanently for someone. The legacy of Sir Berus' family is an infamous kind of legacy one that would give outsiders a tainted view for Cheerup's decision to work for him but somehow it seems like he might have other goals in mind for working for him. And from the looks of it he's quite determined to find what he's looking for.
