No working squeakers
These toys are very durable but the squeakers do not squeak. They were sealed in an air tight plastic bag which permanently collapsed the squeakers.

Squeaky bits broken 😞
Three out of five had broken squeaks. I have extra ones so I’m going to open them up and replace them but it’s extra work when the squeaky bits should be working.

Squeakers not squeaking
Cute but the problem is the bag was vacuum sealed and none of the squeakers work, even after letting them sit a few days out of package 😥
