The Point of No Return

After you vanquish the Complex Parasite, a hole will open up next to the geyser on this floor. Go down the hole instead of the geyser and you will be at The Point of No Return. It could be thought of as the "final rest stop". There is one last geyser here for you to leave if you think you must. There is also the last hole to jump down. Be aware: the research pod will not follow you down to floor 32. If you think you can handle the real final boss, then jump down with your Pikmin. You won't be able to retreat or back down so it is highly recommended that you jump down there prepared. If you lose while you're down there you'll be shot out at The Portal.
