The Lizard is a new fun crystal critter that you can get from the Jaguar Temple. It slithers around as it follows you.
First you go to The Explorer's Camp to enter the Jaguar Temple (you have to have the levitation and invisibility powers).
After you entered the Jaguar Temple you levitate to all of the different plateaus to collect the five Blue Crystals for the second time.
When you have all of the Blue Crystals you will get a crystal Lizard.
NOTE: Kan the Geomancer in The Explorer's Camp can reanimate the critter for you.
NOTE: Make sure to feed it a bug emote every once and a while!
