animations work but the object keeps going to the centre of the map

i just started to learn animations in blender and i got a bouncing monster i imported the animation and made an animation controller and the animation works but the object moves from its location and goes to the centre of the map and plays the animation and its really annoying so i would be grateful for some help

Read my answer about how Unity imports root object:

Your problem is that your root object is animated an applies position on the transform. Add extra root to your object and then move the parent and it will work fine.
