Ankylosaurus

The Ankylosaurus is a limited Mythical pet that only surfaced during the Prehistoric Event, which immediately changes how you should think about it. This is not a pet you farm toward through an egg with predictable odds; it is a window-locked collectible, so its real "cost" was simply being active and grinding the event while it ran. Once that window closed, the only path left is trading, and event-exclusive Mythicals tend to climb in value precisely because the supply is frozen.

For a serious farming build, the value of a pet like the Ankylosaurus is split between utility and prestige. Even when a specific passive is not documented in the data, an event Mythical from a themed drop almost always carries a thematic, high-tier effect rather than basic XP or hunger trimming, so it tends to slot in as a flex pet rather than dead weight. The honest read: if you already own it, keep it equipped or vaulted for trade leverage; if you do not, do not overpay chasing it unless you are specifically completing a Prehistoric collection. Limited status drives its price far more than raw output, which is the trap newer players fall into.
