This also makes Gekko the first character to have something protective.
The HQ Crystal makes its first appearance in this episode.
Night Ninja and his Ninjalinos get a new power: levitation.
The PJ Masks lost their powers (turned their pajamas back to average ones) by PJ Robot accidentally knocking the mysterious crystal statue off while calling Owlette (briefly blinding her in the process), but later, when she and the other PJ Masks saw it for the first time, they decided to put it back in place.
This caused the Ninjalinos to successfully throw Sticky Splats at the PJs while they were losing their powers one-by-one.
Night Ninja and his Ninjalinos discover the PJ Masks' true identities.
