CB 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.
With an active Cruise Boost, SpongeBob can bash-slam from the wooden tikis and reach the top of the first cliff. Then, the player can bash up the rim of the tunnel entrances and reach the end of the level.
