Pig

The Pig is a Rare pet from the Animal Update, hatched from the Rare Egg at a 16.67% chance — effectively a clean one-in-six roll. That makes it one of the most approachable pets a developing gardener can target: the Rare Egg is an early-tier source, and a 16.67% rate means you'll see Pigs regularly rather than chasing them across hundreds of hatches. For a new player building out their first real lineup, that accessibility is the whole appeal.

Its row does flag a named Pig ability, though the underlying effect isn't spelled out in the data, so I won't put numbers on it. Treat the ability as a known bonus on top of an easy-to-obtain frame rather than a confirmed economy multiplier — judge it in-game once you see the passive's actual text.

On a serious endgame team, the Pig is a stepping stone rather than a permanent fixture: Rare tier caps its ceiling, and high-rarity pets with documented growth or sell passives will eventually displace it. But for early progression it absolutely earns a slot — cheap, reliably obtained, and carrying a real ability makes it one of the better Rare Egg outcomes to build around while you climb.
