또또 DDO DDO is the second single from the K-Pop group myB who were under Maroo Entertainment. Originally debuting as a five member, the company added a sixth member for this release. 또또 DDO DDO was released in November 2015 and came in one version. The single comes with the following contents:
- CD - 4 track single
- Photobook
The design of 또또 DDO DDO is very colourful and has a Lego/brick concept for the single. The front cover has the six members in colourful outfits posing in a circle arrangement and the back cover is kept simple with the group logo and track listing. All the usual production credit stuff is listed on the back as well as links to the group's Facebook and Fancafe. The track listing is shown again on the interior but as cute Lego blocks with the Hangul written on them.
