Piece of flexible vinyl tubing of the appropriate size to slide on to the nozzle of your powerhead. Might be able to reach it that way. I had to re-aquascape once after my BTA went into hiding, didn't come out for weeks and was getting very pale & shrinking. Had to flip a sizeable live rock a good quarter turn if not more, and of course that rock was supporting several others. Before that it had stayed put for close to two years and it hasn't moved more than an inch or two since, even after splitting off a clone which also split. All three stayed very close, moved one a few weeks ago in anticipation of sale/frag swap in Kamloops. I was able to prod the foot with a gloved hand long enough for it to release.
