Moth

The Moth is a limited Legendary pet introduced in the Friendship Update, and that origin is the key to reading it. As a Legendary it sits well above the common shop tiers in expected passive strength, and because it carries its own named Moth ability, it was clearly built around a specific effect rather than a generic family buff.

The Friendship Update connection is the interesting part: pets tied to social and co-op content often reward playing alongside others, which makes the Moth a plausible candidate for group-oriented or friendship-scaled bonuses rather than a flat solo-farming buff. If that holds, its value rises sharply in shared gardens and falls for purely solo grinders, so your playstyle should drive the decision more than its rarity tag alone.

Being limited, the Moth is no longer in active rotation and now lives on the trade market, which lifts its collector value above farmable Legendaries like egg-shop pets. For a serious team, treat it as a conditional specialist: confirm exactly what the Moth ability scales with, and if you play socially it can justify a roster slot, while a strict solo optimizer may find a guaranteed-utility Legendary the safer pick.
