I can tell you write now that what you are about to hear will sound very dorky of me but I think it's a good idea. So after your do all your productions and splits,vanishes,reappearances etc. you pull off this little bit as a pretty stupid climax. I mean stupid in a funny, dorky, magical sense here. But as your climax guess what, guess who, appears in your spectators hand instead of all the sponge balls they've held. SPONGE BOB SQUARE PANTS!
Like I said dorky. But all the same it is a change in the sense that instead of 5 or so sponge balls they now have one anatomically correct Sponge Ball Sponge Bob. Me being a weird kind of magician this would be great for me. What do you think?

Sounds like a good idea at some kid party's. Try it and let us know what happens.

I do something similar, but much more mature... not for the younger audience.
I use the Gosh Ding Dong for my college and bar shows.

Dude... I... I don't know whether to laugh or cry. And even if I decide that I won't know what to laugh or cry at. So...How are the reactions.

Okay I will first I have to make him though and that's gonna be the hardest part.

It'd work good for me too. A lot of people always think I am going to say spongebob not spongeball.

That's uber funny Spongebob is awsome.

I love sponge bob, I watch that show all the time, I don't think it's dorky

I actually had the same idea. I've been searching for a sponge Sponge Bob, but have yet to find one, and don't have the time to make one myself. But I thought it was a great idea. I guess great minds think alike.
