A dwarf geyser Vorchun (Grumbler) is located on the slope of the Multi-Colored Griffins, opposite the Pink Cone. Between eruptions, characteristic muffled sounds were heard from the griffin, which became the reason for the name. Described by Leonov (2012) and Zavadskaya (2013). Erupted to a height of 10 cm with a period of about 1 min. In 2014, it was covered by a mudflow.
