How about a little magic?
Mickey's Spellbound Sky is a skydome in Disney Infinity and Disney Infinity: 2.0 Edition. It is inspired by the Sorcerer's Apprentice sequence from the movie Fantasia. The Nutcracker Suite from the said movie serves as this sky's music. It does not have a Texture Set counterpart. It is unlocked from one of Sorcerer's Apprentice Mickey Mouse's Character Chests in 1.0 and when you put him on the base in 2.0. The sky itself is a dark night sky with galaxies and shooting stars, and there is a large ocean that appears below the terrain, just the way it looked during Mickey's dream sequence in the cartoon when the house was flooding.
