Slime – slimy pests that make up for their weaknesses with large numbers (always attacks in hordes). You could say they’re not very goo-d on their own.
Giant Slime – a menacing slime looking for trouble. When defeated – it usually spawns a number of ordinary Slime monsters from its spoils.
Slime Blob – this enormous blob of evil goo has devastating slobber attack.
Bucket Slime – a large slime wearing a bucket (as armor). When the bucket breaks, he becomes angry (rendering somewhat like a “Haste” buff on it).
Slime Queen – an elegant but deadly slime who summon slime minions when attacked.
Skeleton – the reanimated bones of fallen warriors who hunger for battle. Armored and pretty resilient (compared to slime).
Skeleton Archer – even though they feel no pain, they prefer to fight at a distance. The very first ranged enemy unit you’ll encounter. Although tricky (since they attack from a distance), they are not as hard to kill.
Skeleton Mage – cursed with dark magic, these bones empower other enemies near them. Attacks with magic and effectively buffs enemy units near them (both attack and defense).
Spider – these arachnids are fast (walks fast when compared to other units). Try to stop them with ground units or by summoning Heroes to block their path as they can easily overwhelm you in numbers.
Crow (flying) – the first flying enemy you’ll encounter in the game. Crows are able to fly over ground/melee units and past certain towers without being harmed. Their main objective is to breach your defenses.
Poison Spider – their poisonous cloud (area of effect attack) can take down multiple troops.
Warthog – wild hogs out for blood. They are not only fast, they are also outrageously strong and resilient.
Bucker Troll – Though these trolls slow, they are very durable and packs a punch (smashes things). They take time to put down even when multiple units are attacking it.
Giant Slime Mage – Slimes have a habit of absorbing all sorts of things. This one tried to absorb a skeleton mage, and couldn’t quite do it. So now, the combination of the two wreak havoc the best they can as a team.
