Pikalang is a joke esoteric programming language created by Blake Grotewold. It is identical to Brainfuck, except that the instructions are changed into the sounds made by Pikachu from Pokémon. It is one of the many trivial Brainfuck command substitutions. As such, it is a member of the TrivialBrainfuckSubstitution family of programming languages. https://esolangs.org/wiki/Pikalang
