The second sale was on June 23, 2016, when "short" variations of the collars and wristbands were sold of the course of four days.
The third Spiked Sale occurred on November 17, 2016, when "long" variations of the collars and wristbands were sold with special striped patterns for just four days.

The fifth, and most recent Spiked Sale was also combined with the Wild Weekend event. It occurred on June 22, 2017, with the release of four new spike sets for four days only. Unlike the previous spike sets, these were designed with completely different shapes rather than just different colors. This was also the first time that a non-member spiked set was released.
