Animal
Danny stood in the middle of the park, watching Cujo yapp happily, running circles around Danny's feet. He was determined to teach the ghostly pup a trick.
"Sit!" Danny ordered. Cujo just wagged his tail.
Danny frowned. "Come on, that was an easy one. Ok, uh...shake!"
Cujo yapped.
Danny scratched his head. "Um..." He was cut off when Skulker shot an ecto-net at him, pinning him to the ground. Skulker held a green blade up to his neck.
"I got you now, whelp! Your little mutt can't help out of this!"
Danny smirked. "Actually Skulker, my 'mutt' knows one trick that's gonna kick your butt. Cujo! Attack!"
The little puppy grew into the large green beast, baring his teeth and growling at the now terrified Skulker.
"Good dog! Heel! Heel! HEEL!"
Cujo picked Skulker up with his mouth and shook him around so hard his mechanisms vibrated. Skulker found himself being thrown up in the air and was surrounded by a blue light. Danny had managed to struggle out of the net and retrieve the Fenton Thermos from his backpack. Cujo returned to normal size and pounced on Danny, slobbering over his face.
Danny laughed. "You know, Cujo? I think that's the best trick I've ever seen."
