Pet Collector

A console-era achievement for amassing the game's pet-summoning items - the vanity companions from chests and rare drops (Seaweed from jungle crates, the Bone Key, Honeycombs, Wolf Fangs and friends, depending on version). Collect and use them as they surface; guides rate this among the grindier console unlocks purely on drop rates, so treat it as a long-tail collection rather than a session's work.
