Thank you so much for reading!
I've hunted on eBay but can't find a replacement for this zebra, hippo thing.
This one is musical and it was given to my autistic son by his friend when they moved to a different country.
This one no longer plays music and the ones I've found on eBay don't appear to be musical.
If anyone has one laying around I'll happily pay or if someone manages to locate one I'll be eternally grateful!
