Security Tunnel Skip
The Security Tunnel is a sublevel of the Mermalair. It consists of twisting and turning tunnels, covered with flashing disco floors that harm the player. In the center of the sublevel, multiple layers of the tunnel intersect. From the top, the player can fall back down to the start if they choose.
The player can also climb both cliffs to reach the top of the sublevel without entering the tunnels at all. There are two main steps to this process.
First, there is a small ledge on the side of the first cliff. SpongeBob can reach the ledge with a double-jump-spin, and reach the top from there.
Second, there are turrets that move back and forth across the ground. The turrets emit electricity, which can be abused to climb the second cliff. By performing a bash at the right time, the electricity will cancel the bash animation at its apex. From there, SpongeBob can jump onto the turret during his invincibility frames. Before taking damage again, the player can reach the top of the second cliff, and collect the golden spatula.
