If you find it hard to execute the tackle, then try to press and release one button at a time, as you don’t need to hold any buttons to execute it :)
That doesn't seem to be the case, I tried staying in place and pressing x repeatedly and fast, then slowly, then holding it or in staccato, non worked.
Edit: I think I found the pattern.
Edit 2: I didn't know you could open the house basement, I found the tackle by accident on the surface and tried using it in the cave to the right. Thanks for answering.
