In 1977, a German street set was built at Studio Hamburg for German framing stories. Samson, a bear (1978–2009, and since 2013) and Tiffy the bird (1978–2005) replaced Big Bird (Bibo) and Oscar the Grouch (Oskar der Griesgram) as main characters, and the new version debuted on January 2, 1978. The early puppets were built by Kermit Love; nowadays, Sesame Workshop builds the puppets for Sesamstraße. Each episode featured the new puppets interacting with a pair of human characters; consistently one male, one female. The individual sketches of Sesame Street's original American inhabitants remained the dubbed main part of the show, but some were edited to omit intros that displayed words in English (such as The Adventures of Super Grover or the Sesame Street News Flash skits).
