HappyHallowenAnimeFans!MyHighSchools AnimeClub Is Having A Party!!! and i need help?

Well 你 could do
Ciel's and Sebastian daemon symbols from Black Butler
The Japanese symbols for thing like leader (The melancholy of Haruhi Suzumiya) 或者 symbols for cat and meow stuff like that
if 你 feel confident go ahead and try to do some 《K.O.小拳王》 heads on them of 日本动漫 characters
音乐 notes (vocaloids)
你 could also make symbols from animes/manga (a characters weapon 或者 trademark) like a bow and 《绿箭侠》 for madoka (puella magi madoka magica)
你 could also dye frosting 颜色 that would represent a character as well, like black frosting and then 3 white strips for kid (soul eater)
hope this help ^^ they sound yummy!
