A couple of episodes I had in mind. Comment below which plot you liked the most. I might start working on scripts for these episodes and start posting 'em on the blog page eventually.
Adventure Under The Sea- When Lumpy accidentally drops his sandwich down the toilet, Lumpy, Cuddles, Giggles & Toothy must flush themselves down the toilet (thanks to a smart idea by Lumpy) in order to get it back.
Military Fail- When Flaky accidentally joins the military, Flippy & Nutty must break her out.
Role Play Battle- Sniffles, Toothy, Flaky, Cuddles, Lammy, Lumpy, Giggles & Nutty play a Dungeons & Dragons type-game.
Alien Invasion!- The HTF town is invaded by aliens! When Splendid is seriously injured, he passes down some of his powers to Lumpy, Handy & The Mole, with disastrous results!
Beware The Zombies!- In a parody of Zombieland, when Cuddles, Giggles, Flippy, Flaky & Nutty take a trip to the abandoned Lumpy-themed amusement park, they must battle zombies in order to survive.
