Titus seems like a viscet who would love water. Just in general. Water guns, baths, the ocean, pools, anything. Especially water balloons. In summer you'll always catch him having a water balloon fight at least once a week. He's a master at it, too; he's surprisingly stealthy when he wants to be! It's all in good fun, of course, but it's one of the few things that make him really competitive, and he's a hard target to nail when he's immersed in the visions of glorious water balloon victory.
He really enjoys cold drinks alongside the fun, as well. Whenever time out is called he always makes a beeline for the tray of refreshments he's sure to set out beforehand. Lemonade, iced tea, even an iced coffee or two--he loves the contrast of a hot day and a cold sip.
And along another note, he also likes to collect shells. Not very seriously, just whenever he's at the beach and one happens to catch his eye. He keeps them in a little wooden box tucked against his window.
