Funen as Busta teaches Bucky to learn the Purifier technique.

Later in Episode 22, he teaches Bucky to use the Purifier technique after Ash has been transformed into a Trouble Monster by Slash. After Ash is cured by Bucky and Joan regains her sanity for her friend, Funen later transforms back into his mole-like octopus form which he reveals to Bucky and Kai much to their surprise and it also angers Bucky for his actions by removing him in the short blue basket much to Kai's disappointment.

After Bucky defeats Slash for the second time using the Pump Great Jibak in the final episode, Funen returns back to his human form while gaining mole whiskers on both of his cheeks and reunites with fellow Great Children which is a shocked to Pinky from his appearance.

Funen is described as a calm but a wise man towards the Trios children including Kai who has a great respect towards him as their master. He is also shows his coolness towards Bucky when he teaches him to use the Purifier technique during Episode 22.

As a mole form however, he serves as a running gag towards Bucky and the group when Bucky angrily removes him from the small blue basket which he falls off like a small octopus and the other where Kai was dismayed and terrified when Bucky grabs him on the basket after reverting back on this form.
