It is similar to the Tacodile Supreme in form, but instead has a body made out of piled marshmallows, a head made out of a chocolate marshmallow sandwich- known also as a s'more (consisting of 2 graham crackers, 6(?) chocolate squares and 4 marshmallows for teeth) and 2 dainty, 3 fingered stick arms.
It can also breathe fire.
It appears in the credits of Cloudy with a Chance of Meatballs 2.
This animal is a dragon mixed with a T-Rex
