People walking by Orinda Theatre on Saturday took a moment to see what was happening at the theater. Derek Zemrak, the owner of the theater, organized the first ever Krofft Kon, celebrating the works of brothers and puppeteers Sid and Marty Krofft — known for creating children’s television shows including “H.R. Pufnstuf” (1969), “The Bugaloos” (1970), “Lidsville” (1971), “Sigmund and the Sea Monsters” (1973-1975), “Land of the Lost” (1974-1976) and more.
