Ricordea and it's foot question

[gregzz4]

I have a beautiful green ric that split last month
The new piece has attached itself nicely to my LR, but the original critter is still on a piece of rubble that I'd like to remove from the DT as the weird shape of it makes the ric look like a tent
I've tried prodding the foot and then repositioning the rubble, but it just keeps hanging on for dear life, or falling on the sand
It's so strong, it actually broke the Coral Glue on the rubble free of the LR during splitting

Any tips on getting it to move ?
Thanks for any insights

Here's some pics of the split in action

The original piece is very small right now as I was prodding it yesterday
