Vacuum (38.46%)
Twilight affixed the head of the vacuum over the hatch, then stepped back to trigger it remotely. The vacuum sucked the hatch off its hinges and sucked the guard up into it as well.
Turning off the vacuum, Twilight snuck her way into the airship.
“Oh, you made it. Huh, nice. Now look around for something, ah what’s the word?”
“Incriminating?”
“No that’s not it. Evil, that’s it! Look around for something evil looking, so we can prove they’re evil.” Twilight rolled her eyes, but got on with the mission.
In the next room were several ponies in top hats having a meeting. “Alright ponies,” said a stallion with a cut running across his cheek, “We’ve been tasked with developing new weapons for the clan. Any ideas?”
While a conversation certainly worth listening to, it wasn’t concrete evidence of illegal activities, or ‘evilness’ as Scootaloo wanted. She’d have to sneak past them somehow.
