HC loves bags, boxes, cupboards and especially the fridge!
He has a suckle paw, always the same one, he suckles when he's happy.
The neighbours have a mark on their lino he goes mad over too, fights it apparantly! He follows people too and loves jumping through windows.
My friend's horse I used to ride would have a funny about random things at the side of the road, like a bench, and would refuse to move and you had to get off and walk him past!
There was also one particular jump he would never ever go over with my friend who has been riding forever. I learned to canter on him and on my second round he decided to give me a "treat" and take me over it having never jumped before!
He'd never let my friend's twin sister ride him either despite her being just as good a rider, he's throw her.
