Every Pokémon has an entry in the Pokédex telling us what they're like and how they behave. Some are a little... weirder than others.
Dodrio's entry from Sapphire:
Raichu's entry from FireRed:
Darumaka's entry from White:
All of Mimikyu's Dex entries, especially these ones from Sun and Ultra Moon:
(Raichu's FR Dex entry is notably one of the few to mention a real-world animal.)
Dodrio's entry from Sapphire:
Apparently, the heads aren’t the only parts of the body that DODRIO has three of. It has three sets of hearts and lungs as well, so it is capable of running long distances without rest.
Raichu's entry from FireRed:
Its electric charges can reach even 100,000 volts. Careless contact can cause even an Indian elephant to faint.
Darumaka's entry from White:
Darumaka’s droppings are hot, so people used to put them in their clothes to keep themselves warm.
All of Mimikyu's Dex entries, especially these ones from Sun and Ultra Moon:
Its actual appearance is unknown. A scholar who saw what was under its rag was overwhelmed by terror and died from the shock.
A gust of wind revealed what hides under this Pokémon’s rag to a passing Trainer, who went home and died painfully that very night.
