Eerie Flexibility Despite its size, the gug's multiple joints allow it to fit through tight spaces as if it were a Medium creature. While Squeezing, it can move at its full Speed.

Furious Claws [>>] The gug makes up to four claw Strikes, each against a different target. These attacks all count toward the gug's multiple attack penalty, but the penalty doesn't increase until after the gug makes all its attacks.
