Fun-Size Flarendo
Sold by Ditty Fuzeboy. Nuh-uh! Yellow is coolest! It's themed after the original, who's totally gonna beat that stupid gorilla! Mechanical type. Just a little more information (for people like me who have no idea) the two vendors that sell toys/pets are right outside the arena where the Gorilla/Dino fight.
Fun-Size Flarendo is a battle pet obtainable for free from a vendor in the Liberation of Undermine raid once you reach level 9 renown with the appropriate faction.
