I thought I make this for people to share their ideas on what possible stories they have for TLBT. Originally I thought I could put this in the TV section for "what if" episode ideas, but then I thought that some story ideas could also be applied to movies, fan fiction, and maybe even possible RPs.
I thought I share some of my ideas here first for possible TV episodes. I might do fan fic adaptions in the future.

Daddy Littlefoot: Chomper accidentally calls Littlefoot "Daddy" and some of the leafeaters hear, including their friends. Chomper feels bad thinking he embarrassed Littlefoot while Littlefoot thinks about his relationship with Chomper, wondering if he could be considered a parent as he was with Chomper when he hatched and was the first friend Chomper made.
The Sky Color Stone Thief: Hyp and his gang stumbles upon a bunch of sky color stones. Rather than keeping them to himself, he decides to share with everyone in the valley… However the day after… All the sky color stones are missing, and Hyp becomes the main suspect with everyone thinking it was an elaborate prank considering Hyp's reputation. Hyp teams up with Mr. Threehorn to prove his innocence while the gang search for Ducky. Considering what happened before with sky color stones, Ducky might just be the real culprit. Also, this story might go into depth over Ducky’s obsession.
The parent spell: After an argument with her dad, Cera wishes on a flying Stone of Cold Fire for her and her friends to have more authority over their parents. This backfires as Cera and all of her friends parents have turned into hatchlings! Chaos ensues as the gang has to keep their parents safe while Lizzie has to lead the Tinysauruses in her father’s place.
