SpongeBob has been my favourite Show for as long as I can remember. I grew up watching pretty much every episode, and still catch the occasional new episode. I also have been keeping up with the New Games (But have yet to play most of them) like Battle for Bikini Bottom Rehydrated, The Cosmic Shake, & The Patrick Star Game.
Gary
SpongeBob's pet! I love episodes that have gary as a main charcter, or a bigger than normal role like in 'Sleepy Time'. As Sandy said - 'He has such a way with words'. Spongebob's most faithful friend; Gary wouldn't even sell him out for a cookie.
Patrick
Patrick! The only other person that I know who would want a cheeseburger at 3:00 AM. He is one of my favourite characters, especially in the earlier seasons when SpongeBob turns to him for life advice. Just like Gary, he is extremely loyal to SpongeBob.
SpongeBob SquarePants: SuperSponge
The first SpongeBob Game that I played as a kid! I remmber it being quite difficult (at least as a child), so I only ever got a few levels into it. I still pull it up on an emulator every couple of years to play for a couple of hours. Highly recommended to check it out.
SpongeBob SquarePants: Operation Krabby Patty
Another Game that I played really early on. I remember the driving minigame the most. I also believe there was an alternate ending / New Game+ after playing through once. Not sure if I still have this one, but would love to eventually have all SpongeBob games owned Physically.
