I dropped my tamagotchi in my Dog's water bowl. The screen dropped out straight away. I got a tiny screwdriver and undid the back and removed the battery. I then undid the othere 2 screws and took the cover off. I let it air dry overnight then crossing my fingers I put it back together. Wow, it actually worked. I had a line down the middle of the screen, but I was stoaked that it was alive.
WARNING: DON'T USE HAIRDRYERS ON tamagotchis. THEY DON'T LIKE IT!!!!!! IT RECKS THE STUFF IN THE BACK THAT MAKES IT WORK
