Krabby

Krabby (Japanese: クラブ Kurabu) is a -type Pokémon introduced in Generation I.

Physiology
Krabby is a River Crab Pokémon. It is red on top and mostly tan on the bottom. Its signature feature are the two long pincers it has.

Behavior
Krabby is an omnivore and a scavenger; it rarely hunts for itself. It can also act as a filter feeder by harmonizing bacteria in the sand, but this is rare. It is territorial, and in beaches where there is little food, fights between Krabby are common. Krabby also uses camouflage; it can form mucus sacs around itself if threatened, making it seem larger or making it harder to spot against sea sand. It is usually very small, but it makes up for this with its aggressiveness.

Natural abilities
Krabby can have the ability Hyper Cutter or Shell Armor. Hyper Cutter prevents Krabby's attack from decreasing. Shell Armor prevents all critical hits towards Krabby. If one of its arms break off, it can grow a new one back. They are usually found under the sand in beaches.

Evolution
Krabby evolves into Kingler at level 28.

Anime
Krabby first appeared at a beach in episode 13, Mystery At The Lighthouse, when Ash wanted to prove that he could catch a Pokémon alone. After the capture (which involved Krabby attacking Ash's finger), it was automatically transferred to Professor Oak's Lab, because Ash already had six Pokémon with him. To Ash's great surprise, Gary Oak had also caught a Krabby, which was much larger than his. Krabby also appears on episode 17, Island of the Giant Pokémon, when Jessie and James were under the sand. Krabby then pinched their legs.

Trivia
Even though it is the River Crab Pokémon, its Pokédex entries say that it lives on sandy beaches, as well as it is seen in beaches.
