The fambusher split from its ancestor the froot and inhabited a new niche as a top predator in the Flisch Savanna and Krakow Scrub. It changed its diet accordingly and instead of feeding on flying worms it now feeds mainly on the savanna chut. In order to hunt such big prey they work in groups like their former ancestor the velishroots once did. They live in small family groups of 4-12 members which is leaded by an alpha male. When groups meet they often fight for territory, though some fambusher groups also migrate, mainly the weaker ones that cannot hold a territory. When hunting for chuts they usually scare the whole herd with horrible screams and use the panic to catch the smaller members. Then some occupy the stronger chuts while the rest aim for areas filled with blood vessels and that they have easy access to like behind the legs and sometimes in the neck. Braver larger groups tend to attack the stronger chuts, as those often are found alone and leave their guard behind protecting their young. Their eyes have adapted so that one pair is higher for greater view, one pair is more in front for better sight while hunting, and one pair always looks at the sides giving them a very wide view. They use their very large ears both for prey sighting and cooling.
When the chuts are less common or in the areas near the river the fambushers hunt swimming preys. The mothers can still seal their pouches when swimming in order to protect the babies.
