The present disclosure relates to the technical field of water playing toys, particularly to a toy water balloon, which comprises a flexible shell, a flexible cover and an elastic arm. The flexible shell limits a water storage cavity and an opening connects the water storage cavity and the external space of the flexible shell. The outer contour of the flexible cover is larger than that of the opening to seal the water storage cavity. It is only needed to make the toy water balloon deformation by using the opening to expose the water storage cavity. Which results in higher safety and lower production cost. Compared with the non-magnetic toy water balloon, the flexible cover will stick closely to the inner wall of the water storage cavity so that the toy water balloon disclosed in the present application has good sealing properties.
