Enemies have specific attack patterns.

Black bear
Begins to chase you when you get close. It is a larger and faster version of the brown bear and wakes up very fast. It is almost as fast as your character. Dodge it once it begins to chase you and try to escape to a higher level or kill it.

Brown bear
Sleeps until you are near, then it will wake up and chase you by following your movements. Get far enough so they get off-screen and they will stop chasing you and go back to sleep.

Bull
Stands in the same location until you get too close. It will then quickly charge in a line. Their charge is easy to dodge unless they are very close. Bulls will change direction very slightly while charging in order to follow you. They will continue charging until they collide with something or drop off a cliff or enter water.

Cactus turtle
Wanders slowly around a small area. They will never chase you.

Cloud spider
Floats overhead and drops octagonal pools of acid. A purple outline will warn you where the acid will splash, and that area will fill in soon. Acid will kill on contact. There are two types of cloud spiders, green and purple. The green variety drops acid near the area it is floating at. The purple version drops acid anywhere on the map and is usually faster. Cloud spiders cannot be killed.

Giant ghost
Appears if you steal from his grave. He is large, taking up about a quarter of the screen. He is fast and chases you without stopping. He will kill anything else he touches. You can kite him to clear out enemies. It is best to save any grave items for the last part of the level, then sprint to the exit button after collecting them.

Pogosaurus
Chases you are when you get near. It uses bounces to move and can cover a lot of area quickly. They are relentless and can jump over cliffs and water. However they cannot jump over spikes or go up in elevation.
