...I became interested in seeing real turtles doing cute things. So, looking around on YouTube, it didn't take me long to find gems to treasure forever. ♥ Most of them are videos of turtles eating stuff, because, let's face it, turtles eating stuff is one of the cutest things ever! :D
I'll post individual video links as comments, so that responses won't be as cluttered.
Turtles can't digest grains, and apparently corn/maize is even worse for them, though I'm not 100% sure why. Not that it'll kill them if they eat it once, but apparently it's not good for them at all.
Spike made eating popcorn look so harmless though:
This actually made me imagine the fictional turtles (any incarnation) eating and enjoying flowers as if they're popcorn, which would be both cute and funny. :) I mean, the 2K12 turtles ate algae and worms, and already seem to be enjoying raw unpickled cucumbers, so maybe they would like snacking on flowers too? Roses, tulips, chrysanthemums, lilies, daisies, hibiscus...
Imagine this: April and Donnie are strolling the countryside. (In North Hampton, or wherever.) April sees a wildflower, and decides to pick the flower and give it to Donnie, in what appears to be an affectionate gesture. Donnie accepts the flower, and...starts taking bites. Donnie offers to share some flower petals with April, but she politely turns them down. He finishes eating the flower, and they continue walking. — This needs to appear in an episode or comic of some kind. :D
