|Hammie controls an interdimensional portal|
You see - Hammie was a magical creature.
My younger brother and I created a mythology - partly based on Noozles - an animated series that ran on the children's cable television network Nickoledon - the show featured hidden portals and an interdimensional wizard koala that ends up in our world. Instead of koalas, my brother and I made Hammie the star!
Hence the longevity. And the adoration.
