In theory but significant obstacles do tend to show faintly for that reason. It's completely based off the a v p ability. I can accept that slimy physically could hold itself so it's body isn't behind the Mechs however the actual collision with the wall is the issu there. Slimy may not be pinned but in a hunched position he's also going to be launched  off the front of the Mechs like a rocket sticky or not because of a lack of contact points to the Mechs. At least that's how I see  it going down if slimy is in that somewhat awkward position
