I'm the captain of world's fastest ship!

 With MOM and DAD, Captain Wilbur, Grandma Elspeth,

And Vergil.

How about Millicent? I should bring Millicent...

If so, too many girls are on the ship.

 My ship will be loaded with

Spear of African warrior, Glass marbles from Turk, Seashells from Japan.

She's so big so I can drive a car in the deck.

Of course that's a REAL car, you know, because I'll be grown-up then.
