* Like players, Slimes can travel up 1m block heights automatically. Therefore, look for hills and valleys that Slimes may be stuck behind because there isn't a smooth transition in heights. If you find any try to smooth it out for them. If it's a large mountain, often a simple tunnel can provide an adequate path. Additionally, Slimes can get stuck in 1m tall spaces. Like players, they need 2m tall spaces to move, so either fill in the 1m tall gaps (kill the slime with your gun first) or dig out a 2m space.
