How to move a hitbox

Hello,

I have a recreation of the headcrab from Half-Life 1 that I animated using Geckolib+Blockbench. I was going to try to do all the mob ai and logic and stuff to get it to jump at the player, but I ended up just animating a jump that plays when the headcrab attacks. However, the hitbox of the headcrab stays on the ground/ Is it possible to move the hitbox with the animation somehow? Alternatively, if someone has a better idea that would work let me know. Thanks!
