Snacker never bothered me.
Actually, the blowfish enemies in Jolly Roger's Lagoon are what made me so afraid of underwater levels in video games. Not the Unagi from SM64, not Clanker, not Snacker, not the damn starfishes from DK64, but those stupid little blowfish that liked bursting in front of the scene and then exploding. Unlike GoldenJiggies, however, I overcame this fear.
