The sand volleyball at a pallet swimming area in the city of Palma de Mallorca, Spain, was recently covered in dirt and spilled over.
It was the first time such an incident had happened in Spain.
It is not clear if the childrens pallets were loaded into the pool.
The Palma De Mallorcas swimming pool is located near the Palma Palace and the city’s famed Biltmore Hotel.
The swimming pool was recently installed to protect the water quality of the pool from heavy rains.
According to local media reports, around 20-30 kids were playing on the pool on Wednesday afternoon when it spilled the dirt.
The pool was later cleaned up.
The swimming pool in Palma is considered the best in the region, and is among the top 20 swimming pools in Spain, according to the UNESCO World Heritage list.
