Once the common rooms and hallways cleared out, Logan stuck posters up around the dorms.
( Gremlin Tips )GREMLIN TIPS
A few more hints to help you keep your mind your own.
Citrus juice is a soporific for gremlins. We suggest you carry
a bottle around. In case of attack, spray gremlin in face.
DO NOT attempt to touch gremlin once it passes out. Find
a teacher or administrator and report the gremlin so it can be
collected. Lemon juice is ideal, though orange juice or
grapefruit juice will also work.
Gremlins like to hide out and attack suddenly. Get early
warning with a simple gremlin detector! Tie a wool sock to
the end of a stick and hold it out in front of you as you walk
through gremlin-infested areas, such as the common rooms.
The gremlin will be drawn to the wool and reveal itself.
DO NOT USE COTTON SOCKS! Cotton will only enrage
the gremlin.
STAY SAFE. STAY SANE.
ETA: There are also some posters stuck up in the cafeteria, as per
someone's suggestion.
