Project Bacteria Monster: Basil of Baker Street by @Kooshmeister (Bill Hiers)

Basil has been summoned to the English countryside to investigate a rash of disappearances. Finding no clues, he comes upon a nice-looking lake and decide to very uncharacteristically skinny dip. He strips down to nothing but his socks, and, before removing them, bends down to inspect the water and marvel at how lovely it looks to swim in, getting an erection from how naughty he feels at being naked in the wilderness. For shame!

Little does he suspect that he has been spotted by the cause of the disappearances, a one-eyed giant bacteria monster, which has its sight set on adding the Great Mouse Detective to the list of missing persons. And, no, I have no idea what such a creature is doing in Victorian England. But anyway!

Basil realize the danger in time! In naught but his socks and sock suspenders, the mouse who'd planned to take a naked dip into the cool waters of the lake instead takes one into the slimy purple depths of his devourer, a ravenous bacteria monster.
