Alternatives to the busy buddy?

My little weird gelding loves putting my brushes in his mouth when I’m grooming him…specifically the wood part of my sleekez brush. 🤷🏼‍♀️

I’d love to find him something to focus his brain on (wish he had a fidget spinner!) while he’s on crossties. I’d let him hold a brush but I’d rather not have him drop it and spook himself. I’d let him chew on my reins if it wasn’t for being on my second pair 😆

I bought the Thin Line busy buddy earlier this fall, and it was scary and unsuccessful. Did I mention he’s weird? 🥰. He could care less about his jolly ball, and would love to play with the clothes on my back if the wood brush isn’t available. He’d also lick my hand to death if I let him, but I need them both to work!

Any alternative ideas for his silly brain? I know he doesn’t need it, but I think he enjoys something and could use some enrichment!
