Viipii was chosen over Xochi to be the "Ditto" of Pokémon Sage; being able to breed with any Pokemon.
Despite being gendered, it is currently unknown if Viipii can produce eggs of its own species.
Viipii's pale blue color scheme is that of Yotsuba Blue.
Viipii was first created when a contributor requested a Pokémon similar to the canonical Chansey for Pokémon Sage. Its design was to include themes of the Pokémon Sage development threads, 4chan's Pokémon board and 4chan in general. For this reason, mootcat, a cat-like creature used to represent 4chan's founder, is the basis of the design.
Viipii's name is a phonetic spelling of /vp/, the board that is creating Pokémon Sage.
