The image at for example.

https://scifi.stackexchange.com/questions/76994/can-the-turtles-go-inside-their-shells also includes several animated gifs showing cases where it happened.

I think it would be interesting to have an article explaining this ability of the turtles and creating a timeline of known instances where it has been observed.

It could help with tracking ideas like
 * can the turtles do it in every in carnation
 * can all 4 turtles do it in a given incarnation or have only some been observed?

If we can't do an article for it, can I upload the gifs to my userspace to keep track of?

I'm not really sure if there's a better term than head-tucking for it, maybe scientists have one we can move to later if we find out?
