The plot

 They were planning a plot to steal the very expensive diamond staff from the great scroll museum for their master, the hairy mole rat. They live in the  dark oak woods in an underground bunker. When they were plotting their plan they needed to be very smart. The great scroll museum has the world's best security, The heat sensing lasers that will melt your skin, steel gates harder than anything in the world, with guards with tigers to eat off the brains of anyone that comes after hours and way more. They need to know what time the guard’s shifts end and when and where they are going to get in? They were going to get  through the roof. The only security on the roof is the lights and the  invisible lasers. 

That night  they were leaving from their top secret base in their helicopter. They flew straight over the museum  like nothing happened but one of them stayed in the helicopter and the others jumped out with their jet packs, so they didn't set off the alarm. There was one spot where there were no lasers where the  window was, they carefully opened the window with their suction pads so they didn't break the window. 

When they got in there, there were guards everywhere but no tigers so they just knocked the guards out with a baseball bat. Carefully with their lazer beam stick they cut the glass case that was holding the diamond staff They attentively took it. Devastating mistake, one dumb team mate takes a wrong step and sets the alarm of they are souranded with gurds all the way around they were focused on the gurds, but the hariy mole rat comes out of no where and knocks the guards out. They use the grapple hook to get out of the museum without a scratch. The helicopter picked them up and they flew off without a trace.
