Cheetah

Cheetah blurs the line between pet and mutation: it is described as a legendary pet added in the Smithing Event, but it also presents as a Limited fruit appearance where yellow must covers the fruit and yellow particles stream off it, paired with a x5 sell multiplier. The fast, speed-themed visual fits the name, and the streaming particles make it easy to identify in a crowded inventory.

A x5 layer is a respectable mid-tier value boost. It will not carry a sell on its own the way the x20-plus mutations do, but because it applies multiplicatively it meaningfully lifts a fruit that already has good Weight and a rarity mutation stacked beneath it. Limited status is the key detail here, since it means the window to obtain Cheetah is tied to the Smithing Event rather than being permanently farmable.

For chasers, the value proposition is the scarcity, not the raw x5. If you were active during the Smithing Event it is worth keeping any Cheetah crop for trade and stacking value, but post-event you are reliant on the market, so weigh whether a x5 Limited is worth the trade premium versus farmable alternatives.
