How do you fix a hole in a stress toy?

To fix a hole in a stress toy, start by cleaning the area around the hole to remove any dirt or debris. Use a strong adhesive, such as silicone glue or a hot glue gun, to seal the hole, applying it both inside and outside if possible. Allow the adhesive to cure completely according to the manufacturer's instructions before using the toy again. If the hole is large, consider patching it with a piece of rubber or silicone cut to size before applying the adhesive.
