Buy Grow a Garden Huge Rainbow Iguanodon

Description

The Huge Rainbow Iguanodon is a legendary pet in Grow a Garden on Roblox. It comes from the Primal Egg, which has a 32.5% chance to hatch an Iguanodon. The pet was added in the Pet Mutations update on July 12, 2025.

This pet has a strong passive ability called Dino Herd. It gives bonus experience per second to all active Dinosaur type pets. That means your whole dino team levels up faster while the Iguanodon is out. You can boost the XP even more with a Small Treat or Medium Treat. The ability works like the ones on the Night Owl, Blood Owl, and Mochi Mouse.

The Iguanodon is based on the real dinosaur. It walks on 4 legs, and the 2 back legs are much thicker than the front ones. It has a large neck, a stubby nose, and a long tail. It has a hunger stat of 40,000.

Primal Eggs are not easy to get. You can trade a pet with Graham at the DNA Station, or craft one after upgrading the DNA Machine 3 times. This pet is a great pick for players who run dinosaur teams and want faster pet leveling.
