1. It simply did not do that. I wrote that it ducked from the grab and went for the gap. Nowhere does what you've just specified exist. It stuck around until the rock landed, at which point it still had not been grabbed.

2. The gap is still there and close enough to escape through, no clue what you mean.
Somehow though, I think this is tied to how you think Slimy moved forwards into the grab instead of first ducking away.
