Mask's girlfriend...

[Ringading]

is one ugly cat. He's gotta ditch that zero and find himself a hero.

[Dezro]

Don't you mean heroine? Or are you implying that Mask is some kind of gay cat, like Garfield?

[RevSam]

at first i thought it was an ugly cat, but then i asked my cat, and he assured me that if he still had the ability to screw, he would use it on that cat.

It now occurs to me that she already is a hero (or heroine), for chocolate is a dog's poison and she selflessly consumed it to save Giz. Her desire to report Giz to the dog police is probably a ruse designed to save him from something else. In fact, if it weren't for the fact that she goes entire days without wiping chocolate from her face, she would be too good for Mask.
