th--that was from Episode 18 XD The stewards had been shrunk down and sent inside of the robotic steward to see what made him malfunction. And the angry yellow thingies were living butterfly wing scales (I don't even know...) that had gotten inside and were suspected of making him malfunction...and kept kidnapping the little fairy steward gaga was crushing on.

(the scales ended up being innocent and were just trying to bring the fairy up to the brain area because she'd damaged it when she'd fallen in with them....so there was this big "YAY VICTOLY" scene at the end where the scales and stewards all worked together to reconstruct the robot's brain.

THAT IS WHAT IT IS FROM
