You don't need a spreadsheet to feel it: Rainbow Hatch pets change the pace of Grow a Garden. Once you've tried a proper XP-and-cooldown loop, going back feels awful. If you're stuck waiting on skills or watching levels crawl, it's worth looking at team shortcuts like growagardenboosting and then building around the few Rainbow picks that actually move the needle.

Fast leveling that actually feels fast

If your goal is hitting level caps quickly, Rainbow Dilophosaurus is still the headline. The big XP dump is the whole point, and it pairs cleanly with the usual enablers like Peacock or Mimic Octopus. You tap the skill, swap, repeat, and suddenly "leveling session" means minutes, not an hour of half-paying attention. Rainbow Elephant sits in a different category. Most players won't touch one, and that's fine. It's basically a prestige purchase for whales who already have everything else dialled in and just want the flex.

Budget staples and the sneaky cooldown crew

For normal players, Rainbow Frost Dragon is the one that keeps showing up for a reason. Season-pass supply makes it cheap, yet it still delivers solid XP and a cooldown that fits into copy setups. If you're running Mimic Octopus, it feels like free value. And yeah, Rainbow Hot Dog Dachshund looks like a meme, but it's weirdly practical in fast-cycle teams. People ignore it because of the name, then wonder why their rotation still feels clunky.

Mutations and "making the timer disappear"

Mutation hunters usually start by eyeing Ghostly Headless Horseman for Nightmare chances and the passive boost. It works, no argument, but the price can sting if you're also trying to fund the rest of a team. Ghostly Spider is the more ruthless choice when you care about speed. On short-skill pets, it can turn a normal rotation into a spammy one, which is exactly what you want for grinding sessions. Rainbow Corrupted Kitsune is the classic collector trap: cool to own, not required to win.

AFK utility and smart token spending

If you do long AFK runs, Rainbow Chinchilla earns its slot because it keeps skills coming back while you're off doing something else, even if you can't copy it. Rainbow Oxpecker is a simple, cheap way to stack more cooldown help without overthinking it. And for plant mutation setups, Rainbow Phoenix is the piece that makes the whole plan feel instant when you're pairing it with Ruby Squid. If tokens are your bottleneck, a lot of players just top up through marketplaces like eznpc so they can buy the right pet at the right moment instead of waiting for the "perfect" bargain that never shows up.
