Released with Version 1.9.8, the 2015 Poppo event functioned the same as it did in the last Poppo Event. However, a new costume for Poppo was added that was able to be earned after unlocking Rad Poppo, named Dapper Poppo.
The 2015 Poppo Event is a seasonal event that ran from August 10th, 2015 - August 26th, 2015.
- Rad Poppo could be unlocked the same way as it was the previous year. If the player already had Rad Poppo, she would appear on the main menu from the start.
- Once Rad Poppo was on the main menu, a second star-shaped meter would be produced (rather than there just being no meter like the previous year). This meter was filled completely by KOing 9 Bosses as Marie Poppo, while wearing the Rad Poppo costume.
- Bosses KO'd in multiplayer games were worth three times more for the purposes of filling the meter, meaning it was possible to fill it completely after KOing only 3 Bosses, if playing only in multiplayer.
- Once enough Bosses had been KO'd, going back to the main menu would show an animation of the meter filling up to full, and Dapper Poppo would be unlocked. Dapper Poppo would then replace the Rad Poppo on the main menu, and no meter would be there any longer.
