I am so jealous of you guys and your buns who like toys!! Mine ignores most of them like some of yous have said! :'( I've bought so many balls and wooden sticks and throwy things and all sorts which she just ignores or pees on
I have found some though like the post earlier about the towel and digging but I get worried that she pulls strands out and eats it which I have cught her doing =(
Also I saw the same DIY thing as you jwoo and wolfie goes crazy over that too!!! When she wasnt eating the new hay i got her since I ran out and it was the only thing in stock i did the loo ring wrap ting and she ate actually ate the hay to get to the goods. She loved chucking it about and throwing it everywhere and then picking it up and running around with it lol.
Also I dunno if any of yous get this in america but this thing is AMAZING

I think it's the best toy that has't been DIY i've purchased that she will continually gnaw for hours straight! Its a hard corn starch toy which I got for her because she kept going for plastic/rubber/hard things she would find and so i figured she liked that sort of texture. ATM its 1am and she's throwing it about and gnawing at it stilland its so loud shaking the cage lol but she's happy so i'm happy. She also does this weird thing when she picks it up runs around drops it down carries on gnawing picks it up runs some where else and then carries on. It doesn't last long maybe about 2/3 days if she's at it constantly but because its really hard AND its completely natural. It IS inexpensive and I buy it in bulk which gets costly after a while. Plus it keeps her teeth proper trim! Really recommend it!
Also my bunny sometimes chews her willow ball but only when she has chewed everything else its like her last resort.
