Animation alignment

Hi, not sure if I titled this question appropriately.

But basically, I am putting together an animation of an object that grows (for example, a plant that grows up out of the ground).

When I the animation runs, however, it grows past the floor.

For example, it starts like this:

And ends like this:

Here is the animation in action:

Any ideas on how I can keep it anchored to the floor?

Thanks all.

Ok, turns out it’s a pretty simple fix.

When slicing the sprite, set pivot to bottom.
