Weapon And Armor and the Waterfalls?

[Kawaakari]

I don't ever recall getting them hah, maybe I got them on my first run, or second. I never got them on my genocide run and by then it was too late. I didnt get them on the run after my genocide run, and I haven't met alphys now but I can go to here lab; where are the ballet shoes and the weapon???? ( I know they're in the waterfalls lmao )

The shoes are in the room with the black floor and some blue stuffs. There is a room at the far left with four mushrooms and a patch of grass. Go in the grass and constantly press Z to get the shoes. They are a weapon btw

Just keep going and get the frying pan, it is and will always be the best weapon.

Also you can get cloudy glasses and torn notebook from Gerson.

The tutu (armor) is at the first area in waterfall. If you aren't at the place where Undyne makes spears come from underground yet, skip the part in between the curly brackets. {If not, Go to Hotland, go down, and get the riverboat guy to take you to snowdin. Then go to where you fought papyrus. Go right and} find the first waterfall. It's a waterfall with a path and sign nearby. Press Z on the waterfall and go through the new door.
