What's the truth about the anatomy of Pokémon? Instagram user @topherstoll has some ideas about how Squirtle, Wartortle and Blastoise evolved.

The post provides three informative illustrations of the iconic water Pokémons' unique anatomies, indicating details like the sizes and locations of their organs, what they are made of and their functionality. In the description, the fan posits an evolutionary theory that possibly explains Blastoise's distinctive water cannons. According to topherstoll, "Over centuries and centuries of human interaction and deliberate breeding, the natural water expulsion system was expanded until it became dependent upon artificial, pipe-like insertions that allow focused streams of water to pass through them at high speeds."

"Today, these cannons contain mechanical components that interface with Blastoise's physiology to moderate stream size and strength. These components are surgically joined to Blastoise's water expulsion orifices immediately upon evolution," the theory continues. "They seal directly into twin compartments along Blastoise's shell, which terminate in twin muscular valves. Without these cannons, Blastoise are likely to rupture or tear their own orifices, resulting in death."

The artist further extrapolates that "Blastoise have been selectively bred for obedience and utility, and as such they get along well with humans and adapt much more easily to captivity than their two less evolved forms" and that the Shellfish Pokémon "are still a common sight in human cities, and are often utilized in varied roles by police, coast guards, and military forces."

These anatomy diagrams and evolutionary theory are some of the most recent examples of bizarre Pokémon fan content, which explore some of the franchise's more unsettling implications. For example, a YouTube video that shows how to prepare and cook a Bulbasaur went viral earlier this year and a new fan theory explores the possibility of Team Rocket's leader Giovanni being Ash's father.

While weird and outrageous fan content is popular within the Pokémon community, official developments in the franchise that have recently been announced also have fans excited. For example, there is a new expansion set for the trading card game to celebrate Pokémon's 25th anniversary, a new mobile game is in the works and special in-game bonuses -- Dada Zarude and a Shiny Celebi -- were released for Pokémon Sword and Shield in honor of the franchise's latest movie, Pokémon the Movie: Secrets of the Jungle. 

The new movie is available to stream on Netflix alongside other entries in the Pokémon franchise like Pokémon: The Indigo LeaguePokémon: Mewtwo Strikes Back - EvolutionPokémon the Movie: I Choose You! and Pokémon Journeys: The Series.
