Pikachu totally gone wrong

Today as usual, went to school to have some lessons. And as of usual, me and my friends were reading manga from a website. Then a friend of mine, Derek Lim Bo Bo, found a link that showed this Pikachu picture out of the blue.

People trying to enter Pikachu! Oh my Tian!

When we were laughing so hard at the picture, Zhong Ming (serious guy) came out of curiosity as he thought it was just a simple Pikachu. Then after he saw it, he went like "oh ok... (let out a bit of laughter)". For some of you, it might be a normal Pikachu picture, but it is really very wrong. I will not tell you what is wrong for the sake of all the "non-polluted" people out there. Try figuring it out yourself :X

Hint: It appears as a male in cartoon but this picture shows otherwise. Now i am unsure of his/her gender.
