Cocoa Beast

"In the new research of Catpaw Corp. is cataloged a really special type  of Drop-zilla. Drop-zillas becomes corrupted when their souls are too  much damaged and as bad that damage is, worse the corruption in his body  will be. With this, their body has almost half of it covered with dark  jelly or chocolate, sometimes honey...anything they eat while trying to  calm their heart a little. They can't learn a job and can't be in animal  form, but can do diverse little jobs that they learn with experience.  The more special trait about them is that his hair is different  depending of what season they born. It's common to see pieces of  chocolate on their hair or something they like, as their hair are  "jelly" they just sticks things on it xD. Depite it has the same time to  each season, some of them has hard conditions to drop-zillas, turning  hard to survive by their own"
