Pink Dimension

"Lion's Dimension" is a pocket dimension accessible to Steven through Lion's mane, which first appears in "Lion 3: Straight to Video."

Appearance
Lion's Dimension is a vast pink savannah that stretches to a tall pink acacia tree atop a grassy hill. Beneath and within the tree are Rose Quartz's most treasured items. The actual size is unknown.

Contents
Some of Rose Quartz's most treasured items include a VHS tape for Steven, an unknown bubbled object, a treasure chest, a damaged flag with her symbol on it, her sword, and an XXL Mr. Universe Shirt.

Steven now stores many of his own possessions inside the dimension including his bike and helmet, a magician's hat, a long line of handkerchiefs, and a soda as seen in "Rose's Scabbard". As of that episode, the battle flag is no longer in this dimension and is instead kept by Pearl. Rose's sword remains in Lion, now sheathed in its scabbard.

There is no air in Lion's Dimension so Steven must hold his breath while inside.

Trivia

 * The tall savannah grass in the dimension resembles Lion's fur.
 * The dimension in Lion's mane somewhat resembles the Moon from The Legend Of Zelda: Majora's Mask, as both have a seemingly endless field with a single tree in the center. This is likely intentional, as Rebecca Sugar stated in an interview that The Legend of Zelda: Ocarina of Time is one of her favorite games.
 * Despite there being no breathable air in Lion's Dimension, a breeze appears to be constantly blowing.
 * The concept of there being no air reinforces the idea that Gems do not need to breathe.
