Okay, he could handle this whole trapped in a giant world filled with giant people where even the entrance cousin's apartment was just as giant as everything else. He was Zachary Zatara, after all, and Zachary Zatara was not at all freaked out by his new circumstances. Whipping out his brightly colored wand, the tiny magician called (more squeaked, really) out, "Eb a lamron rood!"
The first sign that everything was about to get surreal for Zatanna was probably that her front door was suddenly transformed. It was abruptly shiny and bright purple of cartoonishly rounded and small proportions. The Amazing Zatara would be defeated by no door, and he huffed in satisfaction as he turned the bright yellow knob and made his way in.
Oh, great. This place was as bad as the rest of the world. There were no immediate signs of the sorts of sparkles or bright flowers Zatanna much preferred. At least it was an improvement over giants tripping over him and pinching his cheeks. Maybe there were some giant carrots in the giant refrigerator, he considered as he went on in. His bunnies would appreciate those, surely.
