A hopper device includes a reservoir sized and shaped for defining a cavity therein and has first and second openings in fluid communication with the cavity. The first opening is disposed at a first end portion of the reservoir and the second opening is disposed subjacent to the first opening. An articulatable valve is connected to the first opening and is manually adaptable between open and closed positions for allowing and restricting flow of the paintball mobiles. A spout having opposed end portions is attached to the second opening and terminates away therefrom for assisting to dispense the paintball mobiles outwardly from the reservoir. The present invention further includes a mechanism for heating the reservoir and effectively maintaining an internal temperature of the cavity within the temperature range such that the paintball mobiles can be maintained at a liquefied state.
