Sticks is a lot of things, but gentle with animals is not one of them, so her friends prescribe a pet. She turns her nose up at everything cute in the pet shop and falls for a little robot dog fished out of the trash, who never stops leaking slime. Sticks christens him Buster and declares him perfect.

Within a week he has slimed every member of the team and most of their belongings. Worse, when Orbot and Cubot rob the DangerCo warehouse disguised as Sonic and Tails, Sticks won’t join the fight in case Buster gets hurt, and the pup gets under Sonic’s feet. Her friends make her choose: them or the dog.

Then the doctor himself drops in with a metal chew toy and a confession: the pup is one of his own creations, and the robbery was all about upgrading him. One chew and he becomes a tentacled monster with the team in his grip. Sticks, of all people, wins him back with a stern telling-off, and he sends his maker packing. Sticks sets her pet free on the beach, and Tails’ plan for a pet octopus is over almost before it begins.
