that sounds a bit like Dorian, he’s all about the dramatic flops and a good long lounge. He does binky, but it’s pretty rare usually it’s just little half binkies, same with zoomies. No idea what sets him off when he does either, but it does seem like it is usually when something new and exciting happened that day. He is allowed on the deck when weather is nice and loves it, but even there once he has ran outside he just loafs and sniffs the breeze. He does go explore tunnels if I have shifted them and if my bedroom door is open that will cause him to materialize across the house to see if he can get in. Oh and if I am in a zoom meeting too long and he feels ignored he will madly and amazingly loudly chew cardboard, rattle his fencing, knock things over and generally cause as much ruckus & noise as he can.
I don’t think you need to worry about your bunny, some of them are just way more mellow than others. I think some breeds can be more so than others too… but someone else would have to say which ones do which.
