This won't make your ice cream invincible, but it's enough to keep it fresh for a little bit longer. Ice cream placement within the freezer also can make or break ice cream. The freezer, much like an oven, has a temperature control, but some spots are warmer than others.
Also most millipedes are nocturnal. They are generally speaking harmless but most species have a series of metathoracic glands which produce a repellent substance which they can exude when they feel threatened. In some larger species this fluid can be corrosive and cause blistering of the skin in large doses.
Millipedes are omnivores and seek out both plant and animal-based sources of food. They prefer to eat mostly dead and decaying plant-based matter, but they sometimes can be found snacking away on live roots or decomposing animals when those are the only option.
