This is the only time in the first three seasons that one of the mermaids was injured underwater by normal stuff, proving therefore that they can be. Rikki was hit on the head by a sinking crate and knocked unconscious. Zane rescued her, making the first and only time in the first three seasons that one of the mermaids was rescued by a non-mermaid.
