Enemy that absorbs player life (someone please help, it has been 11 days)

I made this just for testing the animation:

Everything is fine, except:
-The vine has a delay of 3 seconds to appear the first time
-After the vine is done absorbing player life, it doesn’t change its animation, and it never absorbs player life again.

I can’t think of any more information I can give, so… yeah.

What do you mean???
