Pools had given themselves a commanding lead over League Two’s form side after Nicky Featherstone added to Luke Molyneux’s goal early in the second half.
But the Stags turned the game on its head with three goals in 11 minutes as Nigel Clough’s men claimed the points at a foggy One Call Stadium.
John-Joe O’Toole headed in from George Maris’ corner before Jordan Bowery equalised seven minutes later.
And the turnaround was complete within four minutes when Maris’ cross from the left evaded everyone and found the back of the net.
Substitute Gavan Holohan thought he had grabbed a late equaliser only for his goal to be ruled out by the officials much to the dismay of the Pools players.
And here is how Pools were rated on a frantic Boxing Day afternoon.
