Evolution of what is formerly known as Alyssa.

A dinosaur-like female human being always in a ravenous state of hunger after sandwiches, pita bread & peanut butter, and cheese.

Runs in her free time, runs whenever another person tries to outwalk her.

Says everything twice; stomps her foot on the ground when agitated.

Deep.
(Seeing a girl run)
Whoa, look at that Alyssasaur go.
