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.
Many people will be familiar with the pungent smell of the Portuguese Millipede, and it is for this reason that most predators will steer clear. The eggs of millipedes are laid underground in moist areas. From these hatch babies which are usually pale in colour and have less body segments (and legs) than their parents. They grow by shedding their outer skeleton, and emerge with extra segments and legs each time until they have the full complement.
