During the first stage in SpongeBob SquarePants: Battle for Bikini Bottoms Rehydrated at SpongeBob’s Pineapple home, you’re probably stuck in clearing the attic after you spawn the beach ball. The problem is there is remaining red buttons that needs to push and there is a sock at the top of the attic that needs to reach.
It makes other player confused for the next stage because the signage is pointing to moving to the next stage instead for the instruction of the remaining button.
To clear the Attic and get the sock at the top, you need to move the beach ball near the button. You can move it by smashing towards the location of the button.
Then, once the beach ball is underneath, you need to jump off on to the top. Press jump twice to reach it.
Once you’re on the top of the beach ball, jump twice again and smash the red button.
After that, there will be 30 seconds countdown for you to get the sock on the top. You need to go to the springboard and bounce off towards the wooden platform on the top.
Jump to the remaining wooden platform and finally reach the sock.
That’s it! After that, you can go back to the lobby and exit the Pineapple house.
