Chase's Return to Puppyhood and Skye's Desire?

Credit to @ChaseTheBabyPuppy for the idea and allowing me to use the name Princess for Chase. Also this is my first time writing a story like this sk it may not be good

Chase and Skye explore a cave and find a magic totem, Chase touches it and is transformed back into a puppy and everyone but Skye doesn't remember him now Skye has a chance to fafill her deepest desire treating Chase as a baby and a princess.
