*YOU* have a *SPONGEBOB SQUAREPANTS* clock?? OH MY GOSH!!!!! I AM SPONGEBOB! YOU ARE SO COOL!
-SpongeBob SquarePants!!!
Edit: I wish I knew how to help. Maybe you could try finding a place where they can take a look at the *SPONGEBOB* clock and see what is wrong. Was it expensive?? If worse comes to worse you may need to buy another or just exchange that one for a different one. That may work... I'm so sorry to her it doesn't work.

What a shame.
Once again, sorry I can't help.
Try looking on the internet, website or store you bought it from and see if they can help you.
Did the clock come with instructions? Try looking at those again... maybe they have a troubleshooting page.
If I think of something else you can do, I'll tell you.
Sorry!!! I wish it would work or I could help you out.
Hope that was useful information...
