Right on time as expected. Metal cannot physically sigh but if he could....

Metal is already rising into the air as Eggman begins his flailing and sputtering. His turbine displaying the water even further as he drifts over and low enough to seize his creator by the back of his swimming outfit and haul him up and out of the water. Reversing he returns to shore and deposits his creator onto the ground.

Landing as well, Metal offers up a towel. As well as one of the aforementioned hot water bottles.

On second thought, several of them.
