My son is 7 and loves Ninjago. The Ninjago CD's are always the first choice, then the other and then Playmos as Hotzenplotz come, Jim Knopf and Co. This sometimes leads to sentences of me with "You can but you choose a CD or no Ninjago Playmos" start, because I want to avoid the fifth listen to (with) times a day with Ninjago anschliesender discussion and prompt belonged on the floor enact (and woe I forget the name one of the characters). The CD is the first part of the second season. The (single) CD of the first season is not necessary to understanding the story but does round. Anders, however, it looks to the other CD's of the second season, as they continued the story, so do not like the Playmos, Drei ??? or TKKG tell each separate stories. Currently there are three CD's of the second season, the fourth has been announced for September. The contents of the relay is the same as the cartoon series shown in SuperRTL. Personally, I find the radio play but better since the child has to use more imagination.
