Art	Description
	The dolphin sprites from the good ending, found with the seagull sprites in a KosM archive at $24028E. The dolphins are mapped to a different palette from the final game, and no suitable match could be found.
	Super/Hyper Sonic's ending pose, found in a KosM archive at $240B62. Compared to the final, this pose is mapped to the palette used for Super Sonic's ending pose in Sonic the Hedgehog 3 and doesn't cycle. There are also slight differences in the eyes and mouth shape.
