Very very late at night there is a commotion on the roof of the dorms.
Having spent the afternoon
plotting, the gremlins quietly (for gremlins anyway) gather on the roof. Several are carrying suspiciously lumpy bundles. There is a minor argument (with scuffling) before a group of four head off down to
room 230.
Surprisingly, there are only a few fights to hamper the night's work.
( The results can be seen the following morning )*****
Meanwhile, in the first floor lobby:
Four gremlins come hopping down the stairs. One is holding a
catalog, one is holding several sheets of paper and is playing with a shiny silver pen. The other two are fighting over a silver lighter.
The four sit down on the lobby floor and begin going through the catalog. Three of them do anyway. The fourth sits off to the side and flicks the lighter repeatedly.
One of the three gremlins gets bored after a while and starts another fight over the lighter. The other two continue working. At least, they do until the two combatants roll themselves into them and all four scramble about in a pile for a while. One crawls his way out long enough to secure the paper he'd been writing on and then dives back in to the fight.
This continues until there is a noise somewhere in the building and all four gremlins freeze. Deciding that discretion is the better part of valor, they all dash toward the vent leaving lighter, pen and a much abused catalog behind.
