If you leave Curly in the bed in the house in the waterway, she's gone for good, and you can't get her back.

I don't know if she shows up dead in the plantation or not, I might look into it. She'll stay on your back, then drift away like usual after you beat the boss.

If you decide to go through the water passageway without draining the water from Curly, near the end of the area it will say 'her life functions have ceased'.

There's also a video of this on the Doukutsu Uploader. The hitstun will make you temporarily invincible, so when you try to fly up you won't get crushed. Boost up (v2.0 only) onto the first pair of Presses, then get hit by a dragonfly.

In order to get to the door before the rocket is built, go to the platform near the Press gauntlet, with dragonflies trailing you.

If you manage to get to the door to the Last Cave before the rocket is built, it'll say something like 'It's not time to go here yet' and won't open.

I don't know if she restocks them if you talk to her right after Balrog attacks her. If you don't get a life pot from her after Balrog attacks her, but then you talk to her again after you come back from the labyrinth, then she'll give you a life pot and say she'll give you a new life pot whenever you use yours up.

If you never get the life pot from Jenka, her dog in the Plantation will give it to you.

If you talk to Booster with a mimiga mask, he'll think you're a mimiga.

Sakamoto fall on you, it'll push you into the ground. I have absolutely no idea why squids appear when you get the badge.

To get the Alien Badge, beat the fish boss in the sea tunnel without getting hurt.

Then, go to sleep, and when you wake up she'll be sleeping and you have the lipstick.

To get Chaco's Lipstick, check the fire at her house for the first time.

As far as I know they get no response from Curly.

It will show you a secret passageway, press down somewhere at the end to find the underwear.

To get Curly's Underwear, view the map in the room with the bed, save point, and dog in the back room of the bar.

This is not true, the first time I went to Hell I didn't have the clock.

Many people say you need the clock to go to Hell.

Less than 3 minutes: Sue & 'Safety' track. Less than 4 minutes: King & 'White' track. Less than 5 minutes: Toroko & 'Toroko's Theme' track. Less than 6 minutes: Curly & 'Running Hell' track. It is believed that you must get 5'00'00 or under to unlock the Toroko title screen. However, depending on your score you can get other characters and their theme songs to appear/play on the screen instead of the main character.

After completing the Cave Story by completing the special secret stage (Hell), if you have the Nikumaru counter, your best time ranking score will be displayed in the upper-left hand corner of the title screen.
