Poliwag is a Water type Pokemon introduced in Generation I. It evolves into Poliwhirl starting at level 25, which evolves into Poliwrath when exposed to a Water Stone or into Politoed when traded holding a King’s Rock. Take a look below for 26 awesome and interesting facts about Poliwag.

1. Poliwag is a Pokemon resembling a blue, spherical tadpole.

2. It has large eyes and pink lips.

3. Its skin is very thin, but flexible and difficult to puncture.

4. There is a black and white swirl on its abdomen, which is actually its internal organs showing through its semitransparent skin.

5. The swirl is clearer following a meal and will have a white tinge if the Pokémon is affected by disease.

6. The direction of the belly spiral differs by area; the equator is thought to have an effect on it.

7. It has newly developed legs that are poor at walking and no arms.

8. It has a long, thin tail surrounded by a light blue, semitransparent fin.

9. Its tail makes it a powerful swimmer.

10. Because of its ineptitude on land, Poliwag is more likely to be found swimming in small freshwater ponds and lakes.

11. In the anime, Poliwag feeds on salveyo weed, which can only be found on clear lake bottoms.

12. Poliwag is the favorite Pokémon of Satoshi Tajiri.

13. In its FireRed Pokédex entry, it is stated Poliwag has black skin. The Ruby and Sapphire Pokédex entry for Poliwhirl states that Poliwhirl’s skin is covered in oily fluid—if the same applies to Poliwag, it might be a case similar to the common bilberry: the berry itself is black but covered in a wax-like coating that makes it look blue.

14. In The Official Pokémon Handbook, published by Scholastic, the back cover says “Did you know that the swirls on Poliwhirl’s stomach changes direction when it evolves into Poliwag?” However, Poliwhirl evolves from, not into, Poliwag.

15. Generation V changed Poliwag’s base Experience yield from 77 to 60, making it the only Pokémon whose base Experience yield is the same as its National Dex number.

19. Poliwag is based on a tadpole.

20. The spiral pattern on its belly is supposed to represent how the intestines of tadpoles are sometimes seen through their transparent skin.

21. Poliwag is a corruption of polliwog (outdated term for tadpole).

22. Wag may refer to its long tail, although it is worth noting that polliwog literally means “head-wiggle.”

23. Misty caught a Poliwag in The Stun Spore Detour, which eventually evolved in The Totodile Duel into a Poliwhirl and then into a Politoed during Outrageous Fortunes.
