Okay. I can see how Rubble can dig up some trenches to further help drain out the flood waters but how will Rocky have any time to make anything "On the fly" while he's busy opening the sea gates? Shouldn't he be of better help by building up the barriers with tetrapods instead with his tugboat (Has a claw)? Also, shouldn't heavy lifting and loading (e.g. Tetrapods onto a vehicle) be more of Rubble's specialty than of Rocky's?
