Amarok appears to be mean as Miele mentioned, but he is in fact happy, playful, caring and obedient. He is also quite clumsy as he caused some troubles because of his oversize body. Flora describes Amarok as "wild".
Amarok made his debut in "Adventure on Lynphea". Although he was not seen so much, he was seen clearly in the next episode. He was seen fighting against the fungi in the forest of Linphea. Moreover, he bonded with Flora, and since then he was always seen in the season.
Amarok made an appearance in "Back in the Middle Ages", while Flora was trying to push him through the doors and make friends with Squonk but showing his teeth to the Cry-Cry gave him the wrong impression and Flora wanted him to apologize. In which Nex thought this was a bad idea and calling Squonk ugly which caused him to cry tears on Heila and Nex causing the two laugh. In which Amarok turned into his playful nature and started making a mess of everything in the room until Flora told him sit down after the rest of the Winx came in to know what all noise was about. Helia only said that Amarok was playing giving him one of Heila's origami figures to play with.
In "Winx Trapped!", Amarok has finally made friends with Squonk and when he tried to make friends with Critty, she didn't make it easy by walking under a table but when Amarok tried, he knocked it over. When he tried to extend a hand of friendship Critty responded with her claws and quills which caused the Magiwolf to bark in anger. So, to distract them, Helia used his origami skills in which he and Squonk were impressed. It wasn't until Critty shredded Helia's origami castle, which caused Amarok to play his game chase which made a mess of everything resulting in Flora being disappointed in him and Helia helping him out of the table.
Later that night, he heard Kalshara inside the school and tried to wake up Flora and he saw Critty get abducted and at the end of the episode, Amarok was enjoying a party with the rest of the fairy animals and knock over a tray but instead he caught it making Flora proud.
