Whether in the water or out, Ariel can be a bit slippery to catch by force as she knows how to use her surroundings. She is a bit more open to being tied by those she likes and her friendly nature makes it easy to win her over in that regard, so best to approach her that way. The tie to use on her depends on if she's in mermaid or human form: focus on her chest in mermaid form and her legs in human form. Either way, her mermaid tail and legs are her weak spot. She prefers lighter gags and may even sing for her captor, but another tip is to use a gag that doesn't pin her hair down as she also likes having it stroked. She may not seek revenge, but some of her sea friends might if they find out she was mistreated.
