Rabbit toy advice

I use to buy baby keys and wooden blocks but now I cant find any are they unsafe or just stopped making them?

Any other toy ideas?

Hang on... are these toys for your pet rabbit?

I found ttha when I had a guinea pig, she loved playing in boxes and tubes, so I got hold of some cardboard boxes and wide plumbers piping, and she enjoyed running in and out of them like a maze. They're really cheap tto acquire, and you can rearrange the boxes and tubes to run in and out of each other.

I thought this question was going to be about something MUCH different.
