No one, including Apu himself, knows why he washed up on shore one day. Not that it matters mind you. A headstrong forager with a penchant for trouble, you'll likely bump into him wrestling with his next meal. Befriend Apu and you may be lucky enough to partake in his culinary delights.

A gazillion thanks to Malfey for letting me pixelify Apu.
And, of course, to thebeesknees for imbuing the bounce.
