Third-graders at Boston Harbor Elementary School in Olympia Washington were on a mission. They wanted to make sure that Washington had an official state amphibian and they wanted it to be the Pacific chorus frog (Pseudacris regilla).

Every student in Keitlyn Watson's class took part in the project which involved a good bit of research as well as testimony before State Government Committee of the Washington State Legislature.

Representative Brenda Williams, of Olympia, represented her constituency well, as she sponsored and then guided House Bill No. 1069 through the legislative process.

By mid-April, 2007, the legislation had been approved by the Washington House of Representatives and the State Senate.

It was delivered to the governor for her signature on April 17th.

On April 30, 2007, Governor Christine Gregoire signed the legislation, declaring the Pacific chorus frog "the official amphibian of the State of Washington."

The law went into effect on July 22, 2007.
