Wrap your teammate in as much toilet roll as possible before the time runs out!
Get into teams of 2 and choose one person to be mummified. Set a timer for an allotted amount of time, (e.g. 2 minutes). When the timer starts your teammate has to wrap the person that chose to be mummified in as much toilet paper as possible before the timer runs out, covering as many gaps as possible. When the timer stops they have to put down everything and the person in charge of the whole game checks up on how you've done, the winner is the couple that has the most toilet roll on the mummy.
