Across recent December 2025 tier lists, Kitsune, Raccoon, Disco Bee, Ruby Squid, Spinosaurus, Butterfly, and Headless Horseman are all placed in S tier thanks to extremely strong mutation or cloning passives, while Mimic Octopus and Diamond Panther sit comfortably in A tier, and Elephant is a more niche C‑tier pick. All token and trade values below assume a mid‑to‑late‑game trading environment where S‑tier event/gem pets are top currency for high‑end farms.
1. Kitsune
S-tier pet. It steals fruits from other players' gardens, mutates them with Chakra, and has a rare chance to apply Foxfire, creating very high‑value fruits from other people's work. 
- Token value: Very high - commonly valued similarly to other top S‑tier gem/Zen pets and often traded only for multiple strong A‑tier pets, premium cosmetics, or another meta S‑tier.
- Trade value: Typically "end‑game" trade piece; expect overpays in sheckles, rare eggs, or bundles of A/B‑tier pets. Often used as a centerpiece in 1‑for‑many trades with good leverage in trader lobbies.
- Best combo: Pair with Raccoon or Spinosaurus for extra stolen/converted mutations. Combine with Ruby Squid or Mimic Octopus so their copied passives keep amplifying the stolen/mutated fruits.
- Best offer: 3-4 Raccoons; 2-3 Spinosaurus/Butterfly; Raccoon + Disco Bee + Butterfly/Mimic.
2. Raccoon
S-tier pet. It steals/duplicates a random fruit from another player's garden, including premium high‑value fruits like Candy Blossom and Moon plants, giving free late‑game income. 
- Token value: Very high - usually around top S‑tier pricing, slightly below more complex gem/event pets but still premium.
- Trade value: Always in demand by new and veteran players. Often traded for other S‑tier pets or bundles of multiple strong A‑tier pets plus currency.
- Best combo: Combine with Dragonfly, Disco Bee, or Butterfly so stolen fruits also become Gold, Disco, or Rainbow.
- Best Offer: Disco Bee; 2-4 Dragonflies; 2 Diamond Panthers; Huge/Rainbow Mimic Octopus.
3. Disco Bee
S-tier pet. It turns fruit into Disco occasionally, one of the best value‑boosting mutations in the game, passively increasing your farm's income.
- Token value: High – just below ultra‑premium S‑tier like Kitsune, but much higher than standard A‑tier pets.
- Trade value: Popular "meta" trade; often exchanged 1‑for‑1 with other S‑tier mutation pets or 1‑for‑2 good A‑tiers. Stable value because Disco mutation remains a core money tool.
- Best combo: Stack with T.Rex, Spinosaurus, or Dark Spriggan so their high‑value or copied mutations land on already‑mutated fruits.
- Best offer: T.Rex + Spinosaurus; Fennec Fox; 2-3 Mimic Octopus/Queen Bee
4. Butterfly
S-tier pet. It removes all mutations from a fruit and converts it into a Rainbow fruit with five mutations consumed, which can be extremely valuable.
- Token value: High – top mutation‑conversion pet; generally similar to Dragonfly and lower S‑tier gems.
- Trade value: Desired by players focused on big one‑shot harvests. It can be traded for other S‑tier mutation pets or multiple A‑tier utility pets.
- Best combo: Combine with mutation‑spamming pets (Disco Bee, T‑Rex, Hex Serpent) to stack many mutations, then convert key fruits to Rainbow. Works well in high‑mutation "harvest once for huge payout" farms.
- Best offer: 2 Dragonflies; 3 Spinosaurus
5. Ruby Squid
A-tier pet. Continuously copies a random pet passive, effectively giving you an extra "ghost copy" of another strong pet's ability.
- Token value: Very high – one of the most flexible S‑tier pets, often valued on par with or just under Kitsune/Corrupted Kitsune.
- Trade value: Frequently used in high‑level "meta for meta" trades. Expected to fetch multiple good A‑tiers plus currency if the buyer needs copy synergy.
- Best combo: Copy passives from Kitsune, Raccoon, Disco Bee, Spinosaurus, or Butterfly to multiply their impact; Amazing in 3‑pet line‑ups where all three abilities are worth duplicating.
- Best offer: 2-3 Mimic Octopus; T-Rex; Butterfly
6. Spinosaurus
A-tier pet. It takes a random mutation from existing fruits and applies it to one random harvest, allowing targeted spreading of powerful mutations. 
- Token value: High – strong S‑tier, slightly below the "steal/copy" monsters like Kitsune and Ruby Squid.
- Trade value: Commonly traded among mutation‑focused players; can fetch 1 premium A‑tier + extras; Good, stable value, especially in mutation‑heavy metas.
- Best combo: Pair with Disco Bee, T‑Rex, Golden Goose, or high‑value event mutation pets to propagate their best mutations across your farm.
- Best offer: 3-5 Dragonflies or Queen Bees; T.Rex + Brontosaurus
7. Headless Horseman
A-tier pet. Every 20-40 minutes (commonly cited as ~40m), it targets a random nearby pet at level 50. Resets the target's level to 1 and applies one of four Chaotic/Halloween pet mutations (unique to this pet; first pet to mutate other pets).
- Token value: High to very high – limited/event spooky pet with strong trait, so usually pricier than most generic S‑tiers.
- Trade value: Typically traded as a prestige item; common in event‑to‑event swaps. Can pull strong overpays from spooky collectors and mutation enthusiasts.
- Best combo: Run with Dark Spriggan and Spooky Bear for a spooky/chaos mutation garden. Add Ruby Squid or Mimic Octopus so their copied passives keep re‑triggering chaotic effects.
- Best offer: Rainbow/Golden/Nightmare mutated pets; good-sized Mimic for mega-mutated HH.
