Rockin' RiderCandy 2-in-1 Pony Ride-On

The fabric is ripped near the ear of the pony. it looks like it was never sewn. just received for my niece. can i be reimbursed for this?

How do I change the batteries? I feel the battery pack in the head but I can't find access.

What’s the weight limit

Can u take apart the plush doll to wash or clean? thanks
