I have Bikini Bottom Bash!, Laugh Your Pants Off, and The SpongeBob SquarePants Movie. What SpongeBob VHS tapes do you have? Crossover VHS tapes (Nicktoons Supertoons as an example) count in this. I got Laugh your Pants Off from my friend, The SpongeBob Movie from a Goodwill store and Bikini Bottom Bash from amazon.com (Acceptable condition)
NOTE: DVDs don't count in this discussion, though.
