Sorry, this won't save anyone or anything. That's a "stitch" in time you're thinking of. This little beauty is much more likely to have more ominous effects. If you consider getting extra adventures ominous.

This was November 2005's special item of the month from Mr. Store, which commemorates the events of "White Wednesday" (aka the Great Time Fiasco). When used, it becomes a Temporal Riftlet familiar, which behaves like a barrrnacle combined with a potato, and occasionally gives extra adventures after combat.
