Space Mountain Ghost Galaxy

Space Mountain Ghost Galaxy (Chinese: 驚心動魄太空山) is a seasonal Halloween overlay of Space Mountain at Hong Kong Disneyland and Disneyland. It first premiered at Hong Kong Disneyland in 2007, and premiered at Disneyland on September 25, 2009, as part of Halloween Time. The latter will make use of effects previously used for the Rockin' Space Mountain overlay in 2007.

Inside the Space Port, the planet screen at the front of the station has been changed to reflect the overlay, as well. While viewing the planet, a green "storm" appears over the planet, causing interruptions to the video feed. Static appears, then a blue screen, reminiscent of the Windows Blue Screen of Death, saying "SIGNAL LOST," "SEARCHING..." and "SIGNAL ESTABLISHED". Outside on the dome, five projections play, with several Halloween-themed color schemes appearing between these projection shows:

• The first projection shows the dome becoming a dull grey, with cracks and breaks forming on the dome.
• The second projection shows an alien arm resembling that of the nebula ghost running, pushing against the dome from the inside.
• The third projection shows yellow scratch marks appearing on the dome.
• The fourth projection shows lightning bolts shooting up the left side of the dome, then the right, the middle, and finally the entire dome itself. A green grid then appears at the top section of the dome.
• The last projection shows the dome being turned into a radar, with red blotches appearing on the dome, resembling activity of the nebula ghosts.
