Since last year Lego started the Collectable Minifigures series. Each 3 months they bring out 16 unique minifigures in small bags for about 2 EURO each. It’s a fun but expensive hobby since you don’t know what you bought until the bag is open. Clever Lego collectors quickly figured out way the cheat. Each series, there have been 5 so far, contains a mix of city, historic and fantasy themed minifigs. For example in Series 1 there was an Indian and a forest man but also a nurse and a cheerleader in the historic and city themes. In later series figures obviously inspired by existing characters in Film/TV or other entertainment started appear. A female lifeguard looks a bit like CJ aka Pamela Anderson from Baywatch. A green witch resembles Elphaba from the Wicked musical. In the third series an Elf who could come strait from Lord of the Rings and the latest series a Britsh detective who could be the minifigu-red version of Sherlock Holmes reaches stores. At the moment its not 100% sure, the Lego company has a strict policy against leaked images specially on popular themes, but series 6 could contain a genie with magic lamp.
I collected a large part of the first and second series but stopped when it got to expansive for my taste, my collection sits behind glass with my PVC Aladdin figure collection.. Second hand Lego sites like Bricklink people list some of these figures at 5 times the price of a single bag.
