Frolic is the dog Jean gives Matty in Messenger. In Son, Jonas, Kira, Annabelle, and Matthew inherit him as their own after Matt dies. Frolic had two littermates, who sadly died from sickness. Thankfully, he and his mother were healed by Matty.
- While thinking over names for the puppy, Matty considered Liver because Frolic had been the only survivor of his litter; but the idea was discarded immediately due to Matty's disgust for liver and onions.
- Frolic was named by Leader (Jonas).
