[ROBLOX][2007-2012] Spongebob survival game with infection mechanic

Years ago when I was very young I accidentally stumbled upon Roblox. I didn't know what it was or how it worked, I was just trying to find the web game advertised at McDonald's. However, when I played it (as a guest) it was an interesting game. It was a very 2009~ looking game, everything is built out of bricks and such. You would spawn in some sort of shop where you could walk in and step on square pads to buy items. Outside of the shop, you would use a teleporting pad to teleport to a large area filled with SpongeBob enemies. They behaved like basic Roblox zombies but when you touched them you would turn yellow as if you got infected. There were various buildings based on SpongeBob locations, I remember specifically the Krusty Krab and the treedome. You couldn't actually enter them but I remember somehow being able to glitch into the Krusty Krab. That's about all I can remember. Maybe I could mention that the two main areas (big zombie area and shop) were just floating in the air like a baseplate Roblox map? I also vaguely remember a third big area that I never went to but I'm not sure about that. If you guys happen to know it, please let me know!
