You used to live in shell city but you needed a chance. So you move into Bikini bottom as you search for a house you see one next to a pineapple so you move in right away. When you finish unpacking you hear a knock at your door. When you open it you see a sponge. He seems really friendly and happy to see you.

SpongeBob: Hey neighbor I'm SpongeBob! I just wanted to welcome you to the neighborhood! So what's your name?

I reach my hand out to you for a handshake. I'm just so happy you're here
