The given words seem to be unrelated at first glance, but upon closer inspection, it can be observed that all the words except "cake" can be associated with a specific action or movement. "Snake" can slither, "phone" can ring, "tick" can tickle, and "bat" can fly or hit. However, "cake" does not have any inherent action or movement associated with it. Therefore, "cake" is the odd one out in this list.
