Serpent Starway
Free Big Brother
At the very beginning of Free Big Brother, turn around to face a structure behind you. Swim over to it to find a flying enemy with a guitar who shoots lightning wherever you’re standing. There are two panels here that need to be struck with lightning, so stand on them until he winds up his lightning attack, then move and let him strike the panel instead. After doing this to both panels, the structure will open and reveal the secret exit.
Bathhouse Battle
As you adventure through Bathhouse Battle, you’ll reach a spot where you need to make a group of sponges explode a wall. Right after this, take a left on the next rooftop and hop on the nearby tree to spot a burning smokestack. Spray the fire out and hop inside to find the secret exit at the bottom.
