A dovetail split bobber includes a first bobber half and a second bobber half. A horizontally and/or vertically tapered male dovetail projection is formed on the first bobber half and a horizontally and/or vertically tapered female dovetail slot is formed in the second bobber half. The tapered female dovetail slot is sized to receive the tapered male dovetail slot. The split bobber is preferably a sphere, but may have any other suitable shape, such as a cylinder. A stuffed toy eye may be attached to opposing outside surfaces of the split bobber to create a rattling sound, when floating in a body of water. A Velcro split bobber includes a first bobber half and a second bobber half. A hook fastener pad is applied to the first bobber half and a loop fastener pad is applied to the second bobber half.
