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.
However, for the most part, millipedes are scavengers. They eat dead leaves and bits of decaying wood. If water becomes scarce, millipedes will sometimes eat leaves and roots of living plants for the moisture they contain. Although they do not bite, some millipedes defend themselves another way.
