I would love to Strut get a redemption arc. 
I'll add to this Ozzy and Strut train. I'd have wanted them to get in an episode, but instead of Chomper, I'd be interested in seeing Ruby in a lead role talking to them. Actually, the idea I'm about to pose would make a great add-on to an earlier concept I had where Topps is suspicious of Ruby because her kind is stereotyped as egg thieves. Also, all of this assuming that the two brothers aren't straight up dead at the end of LBT II, mauled, maimed, and disemboweled by Chomper's parents. This is preschool hours, the 8-9 AM slot when the show was still running, we can't have too much death.
Suppose Ozzy and Strut get separated in a cave-in or other earthshake related mishap, as the gang are so prone to. Strut is left with Ruby, maybe Ozzy's left with Chomper, but I'm focusing on the former. This would be a scenario a la Escape From the Mysterious Beyond. So the brothers are separated, but Strut and Ruby are still stuck in this cave, trying to find their way out. There's not much food, and Ruby's doing okay, she ate earlier, but Strut, thanks to pressure against eating greenfood from his brother, is hungry and struggling. They come across a small skylight with a pond where a bit of greenfood and maybe even some shellfish are thriving, and Ruby suggests Strut have some. He's reluctant and surprised at Ruby's suggestion.
"Didn't your parents ever tell you things like us're supposed t'eat eggs?" he'd ask.
"No," Ruby would reply. "They told me that some fast runners do and some don't. Fast runners just like you even, all greens and greens all the time. You must have come from very far through the mysterious beyond."
Strut is a little taken a back and in-denial after hearing this, but the ferns around the pond do look pretty appetizing and one bite couldn't hurt, right? Of course, he takes one bite and is gorging himself because finally Ozzy isn't around to bully him out of it.
Ruby, feeling a bit sorry for the hungry guy, grabs a clam out of the water and places it down next to where he's eating.
"Try it," she insists. "It's got a hard shell, just like an egg. You can crunch right through it if you like crunching as much as I do."
Strut is skeptical, but tries at her behest and what do you know, it's not half bad. Strut likes the greenfood, but his brother might just really appreciate the clam. Ruby resolves to take one to Ozzy, just to see.
That's about where my specific ideas end. Yada yada, there's a plot A and plot B, one of which is Strut and Ruby, the other of which is probably keeping Ozzy away from a stolen egg. At the end, Strut gives his brother a piece of his mind and Ruby gives Ozzy the clam. What do you know, Ozzy thinks it's pretty darn good, maybe even better than an egg, but he's a stubborn struthi, so maybe not too.
Pretty rough ideas, but I thought this would be neat, seeing as Ruby and Ozzy + Strut aren't too far off in LBT terms. Both fast runners and traditionally stereotyped as egg stealers when it seems reasonable that they could have been omnivorous and chosen not to eat others' offspring, like Strut and maybe even Ozzy would ultimately here. Definitely want that Strut redemption arc either way. I like to imagine that Strut's a bit desperate and loopy towards the end of LBT II because his brother won't let him eat anything. We all learn a valuable lesson about judging people about how they look and how people can change and all that good, moral stuff.
