Another comic for the occasion!
When dressing up for Halloween, people often mistake costumes for other costumes. It’s not too surprising, since there are many costumes which share very similar designs, despite being from different franchises. Of course, if you planned on dressing up as something original, people would often mention the most generic type of costume to describe yours. It might just be because many people are not aware of the cosplay’s origin.
Berry here, once again, gets called for wearing a witch costume. The first time was with Yogurt. For Berry to hear it a second time, he probably starts to contemplate whether he really is dressed up as a wizard. Well, when I think wizard, I think of a old man with a long white beard who cast spells using a wooden staff of some sort. That’s not exactly how Berry looks like.
