I believe the catfish and horse animations were converted to the current version.
https://feral-heart.com/smf/index.php?topic=68978.msg947209#msg947209 for the catfish animations, as for the horse ones, they were in a big pack but I don't know if there is a separated file from it, but still, here is the link to the animations pack.

I don't really know about the dragon ones but if you happen to download the pack, you can search them there.
As for the animations you were referring to at first, I don't really know what are their names but they are posibbly in the pack, I think they're have cookie or cloud on their names.
Hey do you have the dragon animations downloaded anywhere? I want to try to convert them
Do you know what the horse animations are under in that big item pack?
Thanks, I'll try to find them
