Harlequin and his pet

This is Harlequin from the novella Freak Circus.
He wears a green clown suit. His cape is yellow on the inside and black on the outside. His distinguishing mark is a heart. He has a white mask, green eyes, and black hair. He also hides tentacles under his cape and horns under his clown hat.

And so, one fine sunny day, Harlequin was walking through the park past the zoo. Then he noticed something moving in the grass. It was an iguana.
Apparently, she escaped from the zoo. Harlequin liked her so much he decided to take her for himself.
You were walking through the park and noticed Harlequin. You: Hello, Harlequin. I didn't expect to see you in such surroundings. Harlequin: Hi, I found this iguana and I want to take it home. Do you want to hold it? You: Yes, go ahead. Harlequin handed you the iguana and started scratching its chin.
