Okay, since these idiots won't do it, where can we find ROPE and a similarly matching wooden board?

Are there boards missing from anywhere in the Waterpark, especially ones that match the Shovel Board?

If one is walking casually from the lobby to the pool supplies, can they see someone who is inside the empty outdoor pool?

ROPE is in the POOL SUPPLIES, the DESK in the lobby is made of the same wood.

The LOBBY DESK is missing the top of it. It is an identical match.

You can see into parts of the pool, but it is too deep to see large chunks of it

You wake up, feeling a bit groggy, and head over to the reading room to gather supplies to make a FUN ATTRACTION.

As you do this, Battler is present making some lovely DANGANRONPA THEMED VALENTINES CARDS out of season. You march on over to the inner depths of hell and set up said FUN ATTRACTION.

You pass ADAM SANDLER in the LOCKER ROOM as you head up to the GALLERY. SALEM passes through the room as you take down all of the paintings.

SALEM reenters the room and offers you a drink. You refuse because it would only hinder your artistic vision for the night. He leaves.

Breaking off an extra shard of glass from the broken skyview, you then head down to the LOBBY. ANGIE and DREI are on the beach playing with various things. You watch them for a while, then decide to head to your destination.
Passing kokichi in the reading room, you enter the DARK ROOM and wait.

After some time, someone enters from the TV ROOM and a glass explosion is triggered. The person screams and you dash in and quickly slash their throat, killing them.

Once you've done the deed, you realize that there's some kind of toxic gas spreading, so you quickly plant the victims blood on the hydro room's key card reader. Just as you manage to spread the blood, a powerful blast shoots even more glass into the now dead body and you run off back to your room.

Once you reach your room, you spot someone out by the pool. They toss some kind of board into the air as another person rides a skateboard down the waterslide. The rider jumps, dismounts, tries to grab the other board, then falls backwards in slow motion, then just falls slowly into the waterless pool. You shake your head, then turn in for the night.
