There's not really much I have to say about this one. It's just an underwater level. Nothing super special about it. I'm not a very creative person, so it's nowhere near as cool as some of the other stuff I've seen so far, but at least I'm trying my best and having fun while doing so.
After you get through the main part of the level, there's a pipe that takes you to a sort of miniboss before the end of the level. You need to avoid the Chasing Porcupuffer while also dodging Cheep Cheeps blocking your path and making it more difficult to continue. It's extremely difficult to dodge the Porcupuffer without a frog suit, so in addition to the frog suit you get at the beginning of the level, there's also a frog suit at the beginning of the boss section.
