Strain the canned peaches through a sieve. Add ¾ of the peaches to the large, empty can and puree them with an immersion blender. Freeze the can with the puree for at least 2 hours.
Cut the rest of the peaches into cubes and set them aside for now.
Add the lime juice, half of the water, half of the white gummy bears, and half of the yellow gummy bears to a saucepan and heat everything slowly. Once the gummy bears have melted, add the yogurt and finely chopped mint.
Take the can with the pureed peaches out of the freezer and add the gummy bear yogurt mixture, then refrigerate the can for at least 1 hour.
Add the lemon juice and the rest of the water and gummy bears to a saucepan and heat until a smooth liquid forms.
Take the can out of the fridge and pour the clear jello over it, then add the rest of the cubed peaches. Refrigerate the can for at least 4 hours or preferably overnight.
Once you're ready to serve, turn the can over and let the jello slide onto a plate. It's easier if you prick a hole in the bottom of the can with a can opener.
