I have four SpongeBob plushes. One is the "Babbling SpongeBob" that talks when you press his nose or hand, or flip his lip. Second one is Lifeguard SpongeBob, who has a plastic megaphone attached to his hand; when you hold it up to his mouth, he talks. The third one's a MuscleBob BuffPants beanie baby, and the last one is "SpongeBob SleighRide", another beanie baby that has a little bell inside him so when you shake him, it jingles.
I wish I could get pictures of them, but unfortunately they're in storage. If you look them up on Google though, you should be able to see what they look like.
