Fabric is easily accessible to the spirits, so it just makes sense to use it for a body. These bodies get ripped and torn easily if the fabric is not a durable material or meant for heavy use. Ghouls will often carry a needle and thread with them to do emergency repairs.

You do not need a special MYO slot or item to create this type of ghoul.

Any type of hood or head accessory
A hood is classified as a garment of clothing that covers the back and sides of the head. It can wrap around the wearer's neck. Hoods can be extended and lengthened to become capes and cloaks. Hoods with zip-up closures to cover the face are also allowed along with hoods that have a built in baclava/mask.

Any type of closure that can be reopened
Zippers, buttons, velcro, snaps, hooks, buckles all count. The closure must have a way to reopen. Stitching does not count unless the spirit is spilling out of said stitching.

Any type of filling
Fillings can include foam, polyester stuffing, down, and anything else used in plushies. Ghouls will also insert weighted beads into certain areas like paws and feet to prevent their spirit from becoming buoyant. Unusual fillings can be anything from rocks to actual meat. Depends on the ghoul, but fillings tend to match their personality.

Tag
Tags can be anything from clothing tags to something like a cattle tag. They can also be anywhere on the body, but have to be visible. Tagless ghouls are a phenomenon and extremely rare.

Aquaghouls can also simply be made of waterproof fabric as well. To swim in the water, most of them have easy to access slits in unnoticeable places to put weight in.
For emergency fixes, these ghouls usually carry around some kind of sealant. Then, heat can be used to seal the plastic back together, creating a type of scar.
These ghouls also commonly have webbed paws or hands to propel them through the water.

Any type of closed, airtight helmet or swimming head accessories
Helmets can be made of glass, plastic, or any other hard material.
Goggles, aquabreathers and other types of accessories are allowed.
Hoods are allowed, it's just uncommon amongst ghouls.

Any type of closure that has a seal
Water valves, plugs, tape, sealed holes (glue, caulk, etc) are all parts of aquaghouls. There can be no zippers, no velcro. Anything that will eventually let water in is not allowed. To keep the ghoul safe, it must be airtight and not allow water inside. Liquids spell danger for ghouls since liquids have denser molecules than air does.

Buoyant/weighted fillings
Fillings are usually air and some kind of weight. If using a filling that isn't air, it must be fully contained inside of the ghoul. If a ghoul gets waterlogged, it could mean trouble since they will be trapped at the bottom of a body of water.

Tags
Tags are very tricky to attach to an aquaghoul, since nothing can puncture the ghoul's body. Due to this, bracelets with tag charms are allowed along with necklaces. Sometimes tags can be sown inside of the plastic and sealed, but it is a difficult task and pulling on/ripping the tag increases the risk of a ghoul getting waterlogged.
