Puffy was an abused cricket that had almost drowned but Len found her while he was swimming in the lake with Jack. He took him to the vet and she was saved from the brink of death. Len named her Jack after Jack Larrins because he thought that she was a boy. About a year later, she gave birth to a cricket that was confirmed to be boy by the vet. Len then renamed Jack. Her name is now Puffy. Puffy's cricket's name is Stuffy.
Son. She cares a lot about him, seeing as she gets overprotective of him when Len gave him milk.
Best buddy. They play soccer every weekend. She is grateful to him for saving her.
