Cub Scout dens are named for the rank, other than Bobcat and Arrow of Light, that the members are working to achieve. There are no specific Arrow of Light Dens in Cub Scouts. The Scouts stay in Webelos Dens until they achieve Arrow of Light and bridge into Boy Scouts. So you don’t advance them from Webelos I Den to Arrow of Light Den; they are Webelos the whole time.
There isn’t an AOL den in Scoutbook. Scouts working towards AOL are stay in a Webelos den. Req 1 for AOL says “Be active in your Webelos den for 6 months after completing the 4th grade or turning 10 years of age”
The Den types in Scoutbook are:
