Lettuce Midorikawa is the third member of the Mew Mews formally introduced to the readers. Infused with the DNA of a Finless Porpoise, Lettuce's legs can change into a porpoise's tail while she is underwater, greatly improving her swimming ability and giving her an appearance of a mermaid. In the anime adaptation, this change can only occur when Lettuce is in the presence of Mew Aqua. Lettuce is portrayed as a shy character lacking self-confidence and is the subject of frequent bullying. She is afraid of her Mew Mew powers at first, causing them to go out of control until she is calmed by Ichigo and Mint. The other members of the group consider Lettuce to be a kind and selfless person. As the series progresses, Lettuce becomes a more confident person through the other Mew Mews' regular encouragement.
