Pet door

Figuring she could just take a peak inside, Diana entered the door with Pet toys. But the moment she stepped through, the door closed and disappeared.

She looked around the room, and it was like a backyard, but inside. There was grass, a dog house, even a stable over to the side.

Diana checked the place meticulously, and found herself getting on her hands and knees to check on the dog house. Suddenly, there was a telepathic attack from her captor, and she crawled out of it. She then tried to stand up but failed. She realized that her legs below the knees were not working, and that they stayed fully bent, meaning she had to walk on her knees.

She continued exploring and came across 5 strange items all next to each other.

The first, was a dog leash,

The second was a ball of yarn,

The third, was reins one would use for a horse,

The fourth was a cowbell, connected to an ear tag

Finally, there was a bird cage big enough for her to fit in.
