There are 11 regular issues in total, featuring comics and activity pages. Additional stories have been published in one "Comic-Super-Album," and two smaller "Comic-Taschenbücher" ("comic pocket books," which include up to seven stories). The two "Sonderhefte" ("special issues") as well as the last three regular books (consisting of double issues, combining issues #12/13, #14/15 and #16/17), are reissues of previous stories.
