The instrument construction set consists of colorful, anatomically incorrect and interlocking construction pieces that children can use to assemble a variety of distinctive musical instruments. The set includes a CD of original music, a large metallic whistle, a canister with a top that converts into a tambourine and a bottom that converts into a drum, drumsticks, a washboard rattle, sand-filled shakers and four poseable eyes that turn the musical instruments into characters. The 42 construction pieces are all compatible with other Bonz sets. Launch date: February 2008.
