total,how many animals are there altogether..???''

The best way to answer this quiz is by illustrating your solution.

i hope your drawing is not as bad as this one,LOL..

The drawing's cute..haha..

I posted it on facebook and one of my friends answered it(with animal's arrangement) less than a minute!!!(i took about 5 minutes,and that made me looked kinda of awful,=.=')
so guys,


Good Luck ^^


p/s-i copied this quiz from a manga that I just recently read,it's damn funny..you may try to give it a guess too,hehe..
