You won't catch this fascinating fish floating in Potion Ocean because Trixie prefers to swim in sludgy-green slime streams! Somewhat of a rare breed, she loves feeding on all sorts of strange algae and funny ferns that stick to the banks of The Underground Tunnel slime-ways.

Native to the slime streams of The Underground Tunnels, Trixie enjoys nibbling at algae growths and fickle ferns. This rare breed of fish can change its colour to match any in the rainbow, and therefore spends her time wherever rainbows gather.


  • She got her name, Trixie, due to her three eyes.
  • Her interactive animation does not include her colour changing abilities.
  • Her quote is perhaps referencing the rainbow-coloured streams of water coming out of pipes to the far left of The Underground Disco.
