Based on Starscribe's Ponies After People series.

When the Earth's humans were changed into ponies and other magic-tolerant species, most people were tossed into the maelstrom of time to be returned to their home planet changed at a future date. Three thousand years after the Event, a van of archaeology students en route to the University of Hawaii reappears in the middle of a now-overgrown Honolulu. Now they must come to terms of their new bodies and their new world.

Step 1: Figure out how to survive as ponies, a griffon, and a diamond dog on an otherwise uninhabited island.

Step 2: Unravel the mystery of how we got here, and why we're the only ones in a place normally crawling with tourists.

Step 3: ???

Step 4: Make contact with the outside world and (if we're really lucky) go home to our families back on the mainland.

Simple, right? Oh and there is the matter of a dangerous artifact we have to keep out of the wrong hands. No pressure.
