Earth

Twilight and Spike entered in the bathroom. They explored it. It was small but full of various items: toothbrushes, soap, a mirror, bath gels and much more. She took a shower.

"Uh, Twi? I kinda miss Equestria" Spike said.

"No time for that, Princess Celestia asked me to stay here as long as the spell lasts" she replied.

"But we don't know how much the spell lasts!" exclaimed Spike.

She levitated a bath gel. She accidentally dropped it and it poured out of the bottle.

"Hahahahahahahahahahahaha!" Spike laughed.

"Spike, two words: Calm. DOWN." the purple unicorn replied, angry.

She made a spell that fixed everything. She looked in the laundry machine. There weren't any clothes.

"Spike, you need to focus!" Twilight said, while the baby dragon was sucking the soap.

"Sorry, Twi. I simply like this!" he replied.

She rolled her eyes and looked at Spike while taking the soap out of his mouth. It was bubbly.

"Now let's go to that room!" Spike said, pointing at the next door.
