Jonathan was thinking of being a Mythological being - a creature from different myths.
there were some possible choices for him -
Bigfoot
Satyr
Centaur
Minotaur
Chimera [greek version]
Dragon
Unicorn
Merman
Mermaid
Were-beast
of course, Jonathan always wondered what it'd be like to change into something out of mythology
he was quite fascinated with them that he would sometimes dresses up as one. He wondered how cool it'd be to be a Minotaur and stomp round in the dungeon. On the other hand, He always wondered what it would be like to be a dragon, a unicorn, and he even especially wondered what it would be like to be a mermaid or a merman.
and now, his formula was gonna turn him into one.
but...
