Place the no added sugar marshmallows and reduced fat spread into a microwaveable bowl. Melt in the microwave in 20 second bursts to make sure it's not overheated.
Add the rice krispies to the marshmallow mix and combine fully. Pop in the fridge to chill for at least 30 minutes.
Once the mixture has chilled it will be really easy to shape. Create 15 "body" balls, and 15 smaller balls for the heads. Alternatively, create whatever Christmassy shapes you like!
**If you slightly dampen your hands, the mixture won't stick to them and they'll be even easier to shape.**
Place the heads onto the bodies using a little pressure to stick them. Decorate with your chosen items!
