Snow Globe of Silence

The Snow Globe of Silence is one of Herbert's inventions, which made its first appearance on the We Wish You a Merry Walrus episode. It was set to create a sound-proof dome over Club Penguin Island, so that Herbert could finally be in peace.

Mechanisms
As part of Herbert's plan, he would imprison and impersonate Merry Walrus, so Herbert could drop "presents", which would create a huge dome of ice over the crowd, trapping them all in a sound proof chamber.

Fate
Although it was almost fully operational, Roofhowse caught the last "present" in time. After Herbert getting thrown off of his sleigh, and Roofhowse accidentally dropping the present, Herbert gets caught in his own trap.
