Grendmines are summonable Minions that appear as Chucky's secondary attack in Minion Warfare. The blast of the explosion is medium-sized. The Grendmine's weakness is that it can also be destroyed by the Shockbots' weapons. A good strategy is to hide it in a place that cannot be noticed, or to put it near a narrow passage with barriers covering up the rest of the space. They are similar to Jawtraps.
