Where can i get a small audio recorder like the ones they put into stuffed animals that sing/talk?

I want one for a Chemistry project- We’re making moles(the animal) for mole (6.02214179(30)×1023) day.

It needs to hold about 30 seconds of audio and have about the circumference of a water bottle cap. (to fit into the moles paw.)
Also, where can I buy this? The Project is due October 24th.
We were actually told about the project yesterday and today we traced and cut felt pieces. It’s mostly an in-class project so she can supervise us and make sure we’re getting the stitching right so the rice and stuffing won’t fall out of it. The only part we aren’t doing in class is the decoration of the mole.

It’s due Monday because it’s an easy project (I’m just an over-achiever when it comes to projects like this.)
