Repair connection buttom

Hello! I recently bought a tamagotchi connection at a great price. The problem is that it has a broken button, as if bitten, a slice is missing.
How can I fix it without replacing the buttons with buttons from another tamagotchi?

:kusatchi:

I've never heard of anyone attempting this sort of repair without simply using buttons from a donor device, but I suspect that you might be able to fashion a tiny replacement button-chunk out of something like Sugru (assuming that Sugru can bond to the type of rubber used for Tamagotchi buttons). You'd still have to take the device apart to do so, since you wouldn't want it to stick to the casing while it's curing, and you'd need to have some other purposes in mind for the Sugru because the unused stuff will expire, though.

There may be something else that's more suited to this job, but this is just what sprang to mind when I read your post!
