Since 2008, Girl Scouts of the USA have had five age levels: Girl Scout Daisy, Brownie, Junior, Cadette, Senior.
 In 2011 they added the new sixth level of Ambassadors.
 Girl Scouts move or "bridge" to the next level, usually at the end of the school year they reach the age of advancing.
 They are considered in the appropriate level based on their grade on October 1, the start of each new Girl Scout year.
 There are exceptions for "special needs" but Girl Scouts who are "young in grade" have not been specifically considered.
 Each year of membership in Girl Scouting is represented on the uniform by a small, golden, six-pointed membership star (one per year) with colored background discs which represent a level.
 Girl Scouts used to wear similar uniforms to other groups in WAGGGS.
 Now a white shirt and khaki bottom is accepted for all levels.
The kangaroo is a marsupial from the family Macropodidae (macropods, meaning "large foot").
 In common use the term is used to describe the largest species from this family, especially those of the genus "Macropus": the red kangaroo, antilopine kangaroo, eastern grey kangaroo, and western grey kangaroo.
 Kangaroos are endemic to Australia.
 The Australian government estimates that 34.3 million kangaroos lived within the commercial harvest areas of Australia in 2011, up from 25.1 million one year earlier.
Cub Scouts or Cubs are an age-based section of The Scout Association for young boys and girls ages 8 to 10½.
 This section follows on from the Beaver Scouts (6-8 year olds) and Cubs will move on to Scouts at the age of 10½.
 The section originally opened as Wolf Cubs in 1916.
The pygmy short-tailed opossum, scientifically named "Monodelphis kunsi," is an opossum species from South America.
 "M. kunsi" is a marsupial from the order "Didelphimorphia" and from the family "Didelphidae".
 Although it is a marsupial, it lacks the characteristic pouch that is often associated with this order It is found in Argentina, Bolivia, Brazil and Paraguay.
 "M. kunsi" is considered a smaller species within the family "Didelphidae", which is why it is named a pygmy opossum.
 The young are referred to as 'joeys'.
 The females are referred to as 'Jill,' and the males 'jack'.
 It was thought to have been endangered in 2001, but has since been moved to least concern by the International Union for Conservation of Nature.
Gilbert's potoroo ("Potorous gilbertii"), sometimes called the "rat-kangaroo" or "garlgyte", is Australia's most endangered marsupial and one of the world's most endangered mammals.
 It is a small nocturnal marsupial which lives in small groups or colonies.
 It has long hind feet and front feet with curved claws which it uses to dig for food.
 Its body has large amounts of fur which helps with insulation, and its fur ranges between brown and grey; the color fading on its belly.
 This potoroo has a long, thin snout curving downward that it uses to smell its surroundings; this trait is common in all potoroo species.
 Its eyes appear to bulge out of its face and look as though they are on an angle and its ears are almost invisible, buried under thick fur.
 Male and female body types are very similar and are both within the same size range.
 Adult females range in weight from 708–1205 g (including pouch young where present), whereas adult males range in weight from 845–1200 g.
Joey Scouts, often called Joeys, is a training program of Scouts Australia for boys and girls aged 6 to 8.
 The section is named after a Joey which is a baby Kangaroo.
 Joeys are organized as a "Mob", made up of no more than 20 children.
 A group of kangaroos is called a mob.
 The Mob is led by at least two adult leaders, usually a Joey Leader and an Assistant Joey Leader.
 One leader must be female if the Mob includes girls.
Rover Scouts or Rovers is the final section of the Baden-Powell Scouts' Association for adults aged 18 and over.
 There is no upper age limit for Rover Scouts and both genders are admitted.
 The aim of the section is "to facilitate the growth of young adults".
 Rover Scouts are guided to train themselves, in body, mind and spirit, to become responsible members of their community.
Lone Scouts are members of the Scout movement who are in isolated areas or otherwise do not participate in a regular Scouting unit or organization.
 A Lone Scout must meet the membership requirements of the Scouting organization to which they belong and have an adult Scout leader or counselor who may be a parent, guardian, minister, teacher, or another adult.
 The leader or counselor instructs the boy and reviews all steps of Scouting advancement.
 Lone Scouts can be in the Scout Section or sections for older young people, and in some countries in the Cub section or sections for younger boys.
 They follow the same program as other Scouts and may advance in the same way as all other Scouts.
The pouch is a distinguishing feature of female marsupials (and rarely in the males as in the water opossum and the extinct thylacine); the name marsupial is derived from the Latin "marsupium", meaning "pouch".
 Marsupials give birth to a live but relatively undeveloped fetus called a joey.
 When the joey is born it crawls from inside the mother to the pouch.
 The pouch is a fold of skin with a single opening that covers the nipples. Inside the pouch, the blind offspring attaches itself to one of the mother’s nipples and remains attached for as long as it takes to grow and develop to a juvenile stage.
 Pouches are not unique to marsupials; echidnas also have a pouch.
Cub Scouts is the section of Scouts Australia for boys and girls aged 8 to 10 (inclusive), often known simply as 'Cubs'.
 The Cub Scout section follows after Joey Scouts and is before Scouts.
 Cub Scouts wear a uniform shirt with navy blue panels, and yellow shoulders.
