Teeny is an exceedingly small monster among bootnokks and regular monsters alike, measuring a meager one centimetre tall. He vaguely resembles his distant cousin and close friend Longy, having large eyes for his size. Teeny's skin is beige in colour, and he has a short tail and two short forelimbs. Teeny is just one individual out of an entire species of micro-monsters like him, dubbed the Micro-Goji or Micro-Godzilla.
Teeny later assisted during the final battle, and played a pivotal role in bringing down Kirkos's shield, as he shot his Micro Beam directly at Kirkos's central face, briefly paralysing the Reality Warper and letting the other members of the group get close enough to begin attacking Kirkos's lower tendrils.
