Similar to [[prehensile_hair]], this tag is for a ribbon that is part of one's body and can be controlled like a hand or tentacle.

Using a ribbon that is a separate tool or weapon does not qualify, because being prehensile requires that the ribbon be part of a character's own body.

The flagship example character is the [[Pokemon]] [[Sylveon]]. Its Pokedex entries do specifically mention it using its ribbons like feelers, and it's seen doing this in the [[Pokemon_(anime)]] frequently.
