"We're gathered here to remember.... our dear friend Boaty..... the truly unforgettable vessel that brought us into this strange new competition."

Boaty (named by Paintbrush) was a boat who took the contestants to the island in Inanimate Insanity Invitational.

Trivia

 * Just like Box, Boaty seems to be an insentient object yet others treated as it were alive holding a funeral and thanking it for bringing the contestants to the island as well as mourning its sudden death.
 * Coincidentally, both of their names start with "Bo-".
