How to earn adventure loops and adventure pins:
Cub Scouts earn adventure loops (Lion, Tiger, Wolf, Bear) and adventure pins (Webelos, Arrow of Light) when they complete an adventure.
Cub Scouts (which the exception of Lions) must complete seven adventures for each rank, but the number of those adventures that are electives increases as the Cub Scouts get older. In other words, Cubmasters, den leaders and the scouts themselves get more choice over which adventures they complete as they advance through Cub Scouting.
Here’s what that breakdown looks like:
Lion: Six required adventures, Two elective adventures a scout must choose.
Tiger: Six required adventures, Two elective adventures a scout must choose.
Wolf: Six required adventures, Two elective adventures a scout must choose.
Bear: Six required adventures, Two elective adventures a scout must choose.
Webelos I: Six required adventures, Two elective adventures a scout must choose.
Webelos II (Arrow of Light): Six required adventures, Two elective adventures a scout must choose.
