One person is also injured while another, a boy, is missing, Pahang Fire and Rescue Department deputy director Morni Mamat told Astro AWANI.
Several homes and vehicles were also damaged in the 7pm incident.
The mud flood was caused by continuous heavy downpour, causing the water level at the Sungai Ringlet to rise and breached its banks.

Bernama reported that the deceased was a vegetable farm worker, a Nepali, whose identity has yet to be ascertained.
The injured person is an Indonesian man while the missing person is a boy from Kampung Kuala Kelah, the report said.
Meanwhile, the New Straits Times reported that more than 20 houses in the Ringlet town, Ringlet New Village and Kampung Ulu Merah Ringlet were submerged in muddy water.
The report said about 150 people from 37 families residing at Ringlet New Village were evacuated to the Ringlet multipurpose hall at 10pm.
The affected villages are located some four kilometres away from Bertam Valley where, in October 2013, a mud flood there had claimed four lives.
Electricity to the affected villages had also been cut off and the areas are pitch dark, the report said.
