Princess Luna's Digital Battle

It was a great day in Canterlot. No attacks, no otherworldly beings, it was perfect... Or was it? Not one pony knew what was gonna happen, but enough about this. Anyway, a rift opened up in two worlds. one in Best Buy, and one in Princess Luna's room. Crash! This is what happened...

Crash! At that, Princess Celestia went to investigate. "Ugh. What now?" Celestia groaned. "Sister!" At this, Celestia wondered what happened. "If it isn't Luna, who is it?" Thought Celestia. "Sister!" Princess Luna called again. The Princess of the Sun then zap-teleported into her sister's room. "What happened?" Celestia asked Luna. "I don't know." Luna said. "And what is this?" They said together."" I have no idea." Said the Sun Princess. "Should we ask Twilight Sparkle? "Yes." While her sister went to send the letter, Luna pulled the... Whatever they are into a storage room when she saw a power switch on one. "Should I push this?" She mused. "Oh well. Let us see what this is." It turned on. There were little words on the screen. One said... Roblox? "What is this Roblox?" "Let us push this... Roblox." She tried to push it. Nothing happened. It was then she noticed a... pad? She touched the pad...thing. When she did so, an... arrow appeared? "What is this magic?" She thought. She slid a hoof on the pad. The arrow moved. She slid it to Roblox. Then, she tried to pres the pad. The words Roblox increased.

Two Hours Later....

Celestia had just came back. "Sorry sister. There was a problem with the-WHAT ARE YOU DOING!?" No response. Celestia had to shake her to get her back to reality. "NOOOOOOO! I LOST MY SCORE TO... XxIamDaNubxX!?" The Sun Princess was obviously confused. "SISTER! I HEREBY DECLARE A CHALLENGE!" Said Luna with the Royal Canterlot Voice. "What do you propose sister?" "It will be... On these!" Celestia was appalled. "B-but I don't know how to use them!" "I will have a recess, so you and the Elements of Harmony will learn." "Why them too?" Celestia, once again, was confused. "I can tell. They will help you, because I can play better. Prepare to lose, sister!" *clap clap* they turned to see... The entire Royal Guard. Everyone sat in silence until Luna spoke. "How long have you been here?" "...ten minutes?"
