Apparently there is a whole armada of Spongebob Squarepants alarm clocks, but none of them are a replica of the one used by Spongebob himself on the show; and I’m really surprised by that. Statistically speaking there are “morning people” who want to emulate the sponge’s wake-up routine.
The only reason I can think of as to why this doesn’t exist yet, is that it would be too expensive to have a 3-foot tall foghorn alarm clock parked by your bed. That said it could be smaller (maybe 8 – 12 inches tall) which you could call “life size”, given how small the characters are in relation to us humans.
It must be equipped with the option for the radio or other beeping sounds for the alarm sound; a horn blaring in the morning isn’t for everyone. The face could also be backlit, it has that eye-pleasing aqua color in the show.
