Meet Sydney the Swallow. She's a country girl who has a knack in mechanics due to her family business. She also likes to swim, and sometimes scuba dive, like here.

Pictures 3 "Wha... I... Uuurrr... I feel..."
Picture 4 "How do you feel?" "I feel... Woozy..." "Don't worry about that, Sydney... Heh... Help me find some more frogmen." "Y-Yes, Mistress... I..." "What was that?" "I... Obey, Mistress..." "Good. Hmhmhm..."
Pictures 4 and 5 are alternates.
