Lickitung is a pink reptilian Pokémon with some white designs on its stomach, legs, and hands. It has a bulky body with a long tail and most importantly, long tongue.
Lickitung can have the ability Own Tempo or the ability Oblivious. Own Tempo prevents Lickitung from getting confused. Oblivious prevents Lickitung from getting infatuated. Lickitung has a tongue which is twice its body length which it uses to catch its prey. When Lickitung licks an enemy, it usually causes paralysis. Its tongue is long enough to lick itself clean. Lickitung's saliva on its tongue can easily grip anything.
Long before Lickilicky was added, the official Nintendo website claimed that Luigi from the Mario Bros. series was Lickitung's evolution. This was just an April Fool's joke, but some people actually took it seriously, thus making Luigi a "PokéGod to some extent".
Coincidentally, the generation VI Pokémon Inkay could be evolved at level 30 while holding the Nintendo 3DS upside down, which is similar to the method claimed to evolve Lickitung into Luigi.
