I propose a law of esoteric langauges:

If there exists, in popular culture, a character with a comically limited vocabulary (e.g. Groot, The Librarian in Discworld) then there shall be a Brainfuck variant based on its vocabulary. (In our example, Grootlang and Ook)

That gives us one language for every Pokemon (i.e pika pika, pik pikachu, pikachuuu, pikachu!)

Arguably you're only counting the lower bounds. There are many Pokémon that have at least two different languages (based on English and Japanese names).

That's easy.

Now, automating that by putting enough NLP together to scan social media and news sites to classify popular characters with a comically limited vocabulary and automatically generate a Brainfuck variant based upon said character's vocabulary? That's the hard part... ;)
