There is a glitch in Minecraft pe where when you set the time too low like -999999 the moon breaks and goes insane
To do this:
1. Place a command block and type: /time add -9999999
2. Change to Repeat
3. Place a pressure plate beside it and stand on it until the moon goes weird,
if you stand on it longer, it goes worse, but not too long or the game will lag and also crash
