The big kids like playing with Cyprian and fight over whose game he is going to play. Kateri tries to caox him upstairs to play "tiny kitchen" with her and Audrey tries to appeal to the equine side in him by prancing on all fours and neighing. I think he likes horsies better.
He takes her for walks using her mane as a leash.
They go on rides through the woods
Ocassionally, he'll try the smaller ponies, which ends up in unintended dismounts.
He always wipes his horse down after a long gallup.
And then joins them for a playful frolick in the fields.
