Trivia
- This is the only spinner to include a Serpentine Staff, most likely as a reference to the fact that Slithraa was the original general of the Hypnobrai before Skales took his place.
- This is also only the Serpentine spinner to come with the ninja design for the crown.
- This is the cheapest way to get Slithraa in a set.
