Universe B (A Day at the Beach)
From Jenny Everywhere Wiki
One universe had a "vast landscape" of "lush, green grass" with "impossibly tall" multicoloured trees with waterfalls erupting from them, and "gigantic" flowers, as well as singing fish. It had multiple stars, moons, and suns, and snowflakes turned into confetti.
History
Jenny Everywhere and Bastian once visited this universe, as Jenny wished to show Bastian her shifting powers. (PROSE: A Day at the Beach)
