[You've traveled to Allsand Island; a vast dry island under a scorching sun that is one vast desert with numerous cacti, leafless trees, and strangely shaped plateaus scattered about. This place is swarming with all manner of strange creatures, and you come across one that looks like it should be in the ocean (or in the very least an oasis) opposed to land.]
I'm a large blue fish with a light blue upper half with white flippers and dark blue lower half with a white caudal fin at the end. I have large bulging eyes that protrude from the top of my head with long eyelashes and half-closed pink eyelids.
However, my most striking features are my large pink lips that take up almost half my face, and the shower head that protrudes from the top of my head which I use to bathe myself in droplets of water to keep myself hydrated and cool in such a humid environment.
Despite not having legs, I slide around the stand in an upright position on my tail fin almost like a snake slithering along the sand. I seem to be tired, as I'm now breathing heavily as if I'm exhausted... and suddenly, in a cloud of smoke I immediately transform.
Now my body is significantly slimmed down, making me look more like an eel than a fish. My scales have become a pale-yellow and my bottom half is now purple and paper thin. My face is now long like a horse with a perpetual angry expression, and the showerhead on top of my head has closed up and looks more like a closed flower bud or the esca on an angler fish.
I spot you wandering into my territory, and I immediately begin rapidly gliding across the sand, holding out my flippers ready to slap you silly for daring to trespass onto my territory! For a fish out of water, I sure am fast!
