Update - After this the Zoo replied to me directly and got into contact. They shipped a replacement free of charge. Was pretty happy with the response from the Zoo in the end. Thanks Oregon Zoo. I'll up the rating from 2 to 4 stars.

Had a good time but bad taste left in mouth when we got back to Australia and my daughter had lost her Otter toy we purchased from the zoom store. Since we got home have contacted the zoo via email, their online shop and phone to see if they could help a little girl who lost her Otter.... Still waiting for a response and it's been 3 weeks. Pretty disappointed with the zoo not bothering to respond.... Won't be back
