Of course, Max(Z3) is Maxwell and Wo-class kinda resembles Cthulhu but the "canoe" and the "dead" Ashigara are references to memes in the nicovideo TAS community.
The "canoe" is supposedly a doni and it was used for movement and warping until better alternatives were found. Since it was stylized "ドニ" it was really quick to pull out.
The dead winged Ashigara is a reference to the "Dead Lion" running gag in a particular TAS which was one of the TAS that gave nicovideo some interest in Scribblenauts. It has since turned into a meme in the community when they started using the dead lion for pretty much anything.
