Context, Naruto is doing an ecological survey as part of an S Rank mission. Killer Bee is with him and they both are at the armadillo which is shy and is curled up. Killer Bee doesn't really care and just wants things over with so he says they should mark down female since the armadillo has a soft voice. Naruto says they should mark down male because the kanji for male is on the shell.
They ask the armadillo what parts it has and it says its private parts are private.
Unrelated to this, the entire island (which is also a turtle) gets flipped upside down, thereby 'switching heaven and earth' which causes all the animals to get surprised and jostled. Armadillo is unfurled in a stunned state and has a big penis. Satisfied, Naruto marks male to finish the mission.
