Both hotter and larger than Old Faithful, Old Parker is a geyser located in Griffin Crest. It erupts every forty five minutes. For some reason this was deemed to be a suitable area to build an EMP safe zone.
As they arrived at Griffin Crest, Charlie Burns and Cody watched Old Parker erupt, though the Chief had to chase a squirrel away from it. When the Rescue Bots came crashing through the fence a short time later, Heatwave was short-circuited by the EMP field and came to a halt right on top of the geyser. During their later rescue, Chase used a bubble tent to protect himself and Heatwave from the geyser's eruption.
