Iguanodon

The Iguanodon is a legendary pet that came from the Primal Egg during the Pet Mutations update, hatching at a friendly 32.5% chance. That is an unusually high rate for a legendary, almost one in three, which puts the Iguanodon firmly in the easy-to-obtain category rather than a chase pet, assuming you had access to the Primal Egg while it was available.

The wrinkle is the past tense in its origin: it was obtainable from the Primal Egg, meaning the egg is no longer in active rotation. So while 32.5% was generous when the egg existed, fresh supply has dried up, and players who did not hatch one during the Pet Mutations window now rely on trading. That combination of a once-common drop and a now-closed source tends to keep value moderate rather than premium.

The data does not record a specific ability, so I will not assign a multiplier; confirm the passive in-game before committing it. On a serious team, the Iguanodon is a solid legendary backbone thanks to its accessible 32.5% history, but it is the kind of pet you ride through mid-game and then upgrade past once you secure mythical or divine companions with stronger documented buffs.
