Instancing not working the way I want it to I am studying blender and I am at the instancing part and I am literally following the instructions on how to instance step by step and it is not working for me. These are the steps on the documentation 

I created a cube and scaled it and then I added an icosphere and then made the ico-sphere the parent of the cube 

And then I instanced it and this is what I got[![enter image description here][3]][3]

I don't understand what I am doing wrong i followed everything the way they did it on the docs what's the matter?

When I put the cube in the center same position as the icosphere I get this. FYI I want to create a ball with tentacles just like they did on the docs

You need to rotate the tentacle in Edit Mode so it aligns properly.  


  Orientation of the tentacle was adapted to the vertex normals of the parent mesh
   (tentacle was rotated -90° around the X axis in Edit Mode).

Step 01 - Set up Parenting



Step 02 - Rotate tentacle in Edit mode. I changed pivot point to 3D cursor for this.
