Goldie (Onyx)

Sarcosuchus, pet to Goldie

Can change size, but is usually the size of a sack of potatoes. (For Goldie to hold him easier)

His internal organs and blood are all the same liquid. His belly is see through to allow others to look into his "liquid body". The liquid will dissolve anything it comes into contact with.

Onyx is very dog like in behavior, loves treats and wags his tail when praised.
