So, I remember this 3D browser game I used to always play when I was around 3 yrs. old as shown in the title. I remember it was most likely an island-based game. It was also MAYBE a Shockwave game, considering that it was pretty big back then in 2008/2009 (I’m pretty sure). There was also a game room with some arcade games and a patterned carpet floor. Also, the last thing I remember was a room that was like a ice cavern. Sorry, that’s all I could remember, hope you can find something.
No rush, but did you find anything? And by the way, it is not Poptropica, Club Penguin, nor is it anything popular or was popular.
Could it be SpongeBob SquarePants 3-D Pinball Panic? You were 3 at the time and you said around 2008/2009. One thing is that the game was released in 2004, but it could've stayed on the website until around 2008/2009.
