Animal " For other things named " animal " or " animals " , see the disambiguation page " Animals are LEGO pieces and figures which are designed to represent and resemble animals . Just as regular minifigure s portray humans , there are also specific figures and parts which depict animals in the LEGO Universe , which are usually made up of specific or custom LEGO elements instead of being composed of standard pieces . Animal figures may consist of just one single element or piece , or can consist of a whole complement of special parts . Not all LEGO animals were made up of special pieces or even one single dedicated element . There were also some animals that were built of universally usable pieces . But those creatures would usually appear in only one set while the other animals could be reused more often due to their more simple and standardized design . History . The first purpose built animals designed for and to scale of minifigures were the horse s introduced in several " Castle " sets in 1984 . These first horses were only available in white and black . A brown version was introduced in 1988 . Over the course of the next decade another two with different colouring were released but the basic form is still the same . There were no new animals until the advent of the " Pirates " theme in 1989 , when the monkey , the first shark , the first bird , and the first octopus were introduced . The bird was printed with a parrot pattern and also its shape had the basic appearance of a parrot . Nevertheless , the same piece also served as generic " bird piece " and was released in various colours to suit its many different functions . It is still in use today . In the 1990s a greater variety of animals were introduced . Many of them , such as cat s and dog s , initially appeared in " Belville " sets but were later also used in normal " LEGO System " themes . There was also a growing number of sea creatures like octopi , available in " Aquazone " sets , and dolphin s , both introduced in 1995 , and also the manta ray and the sawfish , both included in " Divers " sets . Smaller single - piece creatures such as crab s , scorpion s , spider s , snake s , starfish , and bat s also made their first appearances in the 1990s . There was also a small pony that was released in just two " Paradisa " sets in 1996 . All of these new animals , except the sawfish ( which was basically a shark with a new head - piece ) consisted of only one single piece . The only more complex new animals from the 1990s were the dragon and the crocodile . The introduction of the " Harry Potter " theme added the first owl s to the complement of LEGO animals , as well as several mythical creatures , such as the Hippogriff , a 3 - headed dog , and a Hungarian Horntail dragon . Another new dragon was introduced in the new " Castle " line from 2007 . The new " Vikings " line from 2005 brought three different dragons , the Fenris wolf and the Midgard serpent , but those creatures rather fall in the category of non - reusable designs that were only designed for the respective set they appear in . The same can be said for the bigger sea creatures included in the " Aqua Raiders " sets from 2007 . There were also several dinosaurs released in sets of the " Dino Island " , " Studios " , " Dino Attack " , and " Dino " lines . More conventional animals introduced in the 2000s include two versions of a rat , a frog , an elephant , a Polar Bear , and a wolf , that would later become a police dog . A very rare animal was a lemur that was only available in the Shop - at - home set 3828 Air Temple . All of these animals except the elephant are single - piece designs . 2009 brought some new animals , such as the first LEGO cow s ( available in either Reddish Brown or Black and White ) , a small fish and a new shark , that is substantially bigger than its predecessor from 1989 and can now swallow a whole minifigure . Many of the existing LEGO animal designs were used to create wildlife in the game LEGO Worlds . List of LEGO System Animal figures . Dinosaurs and other Prehistoric Creatures . LEGO dinosaur were originally introduced in the " Adventures " line in 2000 . Later variations of dinosaurs would come to follow . Virtual animal figures . Many LEGO software programs and games feature virtual animal minifigures which have never been physically created or released , such as a Llama or a Lion .

LEGO ' s DUPLO line also includes animal figures which are not considered to be minifigures since they are traditionally not included in the LEGO System Line . Unlike regular LEGO minifigure animals , DUPLO animal figures are designed to be big enough as to not pose a choking hazard to small children , much like the rest or the pieces in the DUPLO line . DUPLO animal figures usually consist of only one piece . Many DUPLO adult animal pieces include a baby counterpart .
