A vibrant cartoon with colours and smooth animation. The tin tea kettle was just starting to whistle when Arthur noticed his cat, Barnaby, staring intently at the kitchen wall. It wasn't a mouse or a stray beam of sunlight catching his eye. Barnaby was watching a tiny, luminescent blue door-no larger than a playing card-that had materialized right above the baseboard next to the pantry. Arthur turned off the stove, set his mug down, and lowered himself onto the cold linoleum floor to get a closer look. As he leaned in, a microscopic brass latch on the tiny door lifted with a faint click. The door swung open toward him, revealing a warm, golden glow inside and the faint, unmistakable smell of freshly baked cinnamon rolls. A tiny hand reached out from the opening, tossed a single, pinhead-sized sugar sprinkle onto the floor in front of Barnaby, and pulled the door shut. Barnaby sniffed the sprinkle, ate it in one tiny bite, and sat down to wait. Arthur smiled, pulled a chair up to the wall, and decided his tea could wait until he saw what came through the door next.
