Amazon Studios is expanding its slate of original kids slate with full series orders for Sid & Marty Krofft’s Sigmund and the Sea Monsters (pictured) and The Bug Diaries.

Based on the popular children’s books written by bestselling American author Doreen Cronin and illustrated by Harry Bliss, preschool-targeted toon The Bug Diaries follows the comedic, observational adventures of three best bug buds, Fly, Worm and Spider.

Sigmund and the Sea Monsters, meanwhile,is based on the legendary Krofft brothers’ classic 1970s Saturday morning TV series of the same name. Aimed at kids ages six to 11, the new version kicks off after two brothers, Johnny and Scotty, and their cousin Robyn, help friendly young sea monster Sigmund elude the dastardly hunter Captain Barnabas (David Arquette).

The show is executive produced by Sid & Marty Krofft (Mutt & Stuff, H.R. Pufnstuf, Land of the Lost), who enlisted Jonathan Judge (The Thundermans, School of Rock) to direct the pilot and Garrett Frawley and Brian Turner (Santa Baby) to write the new teleplay based on the classic series.

Both series will be available to Prime members for streaming across the Amazon Video app for TVs and connected devices including Amazon Fire TV, mobile phones and tablets, or online at www.amazon.com/originals.
