- This is the first Trap Monster that is also a Tuner monster. It is also the only Trap Monster that can be activated only once per turn.
- This is the first Level 2 Trap Monster.
- This card's name is a portmanteau of "shape shifter" and "sister", referencing this card's feminine, amorphous appearance.
- Oddly, this card's artwork was not edited in the International version; namely, some of this monster's horns appear demonic and the jet-black glop on its upper chest is strongly in the shape of a bra.
