Nautical theme thank you favors. but maybe have it say "tank you!" I'm not a fan of party favors, they're redundant in my opinion, but the mint life savers as part of the baby shower would add a nice touch for the theme.
Chips Ahoy (Ahoy, it's a Boy!) for a boy, nautical-themed baby shower.
I remember doing sth like this in class once, for extra recess
