Gremlin

So this is a we poem that my dad wrote for the students of the school he used to work at. He used to be the janitor.

Wether I'm Gismo or Stripe or the Bat-out-of-hell,

Which one i am,

You never can tell,

Gismo is cute

He's cuddly and kind,

Stripe is evil,

And nasty as slime,

The Bat out of hell you'll never see

But which one am i?

Am i all three?
