Each 2-piece set is window-boxed for collectability. The Bikini Bottom anniversary collection includes 1) Mr. Krabs & Pearl 2) Barnacle Boy & Mermaid Man and 3) Spongebob & DoodleBob. Spongebob and friends were created in 1984 by a marine biologist, Stephen Hillenburg, calling on his expert knowledge of ocean life to give each character traits of the species they embody. World famous collectible company NECA worked with Paramount and Amazon to create these two-piece sets to bring the characters to life in full color. Three sets include six characters in total with limited availability.
