The plug mandrel body includes a bore, a flow port fluidly connected to the bore, and a sleeve adjustable from a first position to a second position. The sleeve prevents fluid flow through the flow port when in the first position and allows fluid flow through the flow port when in the second position. The plug is releasably connected to the plug mandrel body, wherein the plug is configured to be released from the plug mandrel body by fluid flowing through the flow port.
