Robin and Starfire - Swimming Lessons

Back in the Teen Titans' early days, when they were still establishing themselves as a team, Starfire was curious about the pool that Cyborg had built outside of Titans Tower when the other Titans wanted to relax or get some exercise in.  However since she was never taught on Tamaran or on Okaara as part of her military training, she couldn't swim.  So she asked Robin to teach her how.  Although scared that at first she would drown, Starfire eventually got the hang of it.  

Side note: In the comics and the cartoon, Starfire wasn't seen swimming until issue 7 of The New Teen Titans, so I felt that having Robin teach her how to swim would be helpful, plus it's just cute in my opinion.
