I definitely wouldn't submerge any bullets myself because of the wiring, but it would probably be ok to rinse just the bunny part in the sink if necessary, or wipe it down with a damp cloth.
After looking at mine, it looks like water could easily get into the sleeve, but it doesn't really appear that any could get into the actual bullet. Certainly, keep the controller out of the water!
My question is: can I immerse the whole toy in the water or just the bunny part (and not the battery part)? Thanks!
I'm not comfortable with submerging mine. I've had it for quite a while now and I've never tried it in the bath or anything. It just doesn't look safe. I run the bunny part under water briefly when cleaning it, being careful not to get the cord wet.
