If I'm reading correctly these scrapped Pokémon (codenamed Peanut 1 and Peanut 2) were designed by Kanako Eo (江尾可奈子)

GOD the peanut pokemon is such a simple yet smart design, every element of it has a clear purpose and flows together perfectly. i need to absorb the designer's powers

Context:
This lost included an edited image that shows how this Pokemon’s design is based on peanuts, how they sprout, and how they flower.
