Care to Guess

Message:

"The bag and its magic must be kept a secret. Someone almost blew it at show-and-tell with a lucky guess. When used, the magic bag's power to save one of his friends, it caused a vision of his future self to appear with a reminding "shush!" This caused a rocking of the bag's washtub form used as a boat."

The bag may only be used for good and keep secret. The Russians tried to copy it with a computer but used cheap materials, not true Egyptian Wool from the bag's origin.

So who was the USER? He had a jingle theme song, about this "bag of tricks."

Yours,
