Think up a creative and weird alternative way for me to protect my phone if I don't want to purchase a phone case.

If you want to protect your phone but don't want to purchase a phone case, you can make your own by using marshmallows and toothpicks. Use the toothpicks to secure the marshmallows around your phone and make sure that they fit snugly around your phone. Marshmallows are a good choice since they are very soft and squishy and will absorb the impact if you drop your phone.
