The Prypiatosian-B Containment Suit is a special Level 3[DM 1] armored suit that contains Prypiatosian-B inhabitants and weakens their radioactive powers. It is most likely made out of Lead and Beryllium.
Containment Suits are used to prevent radiation from leaking out, and function as prisons on the Prypiatosian-B's home planet to prevent Prypiatosian-B criminals like P'andor from doing any major harm.
Prypiatosian-Bs are unable to phase through its material; Kevin later used this to his advantage by absorbing the suit's material so as to bypass P'andor's intangibility and thus hit him.
In Hot Stretch, the Kraaho managed to open NRG's Containment Suit with their bare hands. The suit was later opened again in The Frogs of War: Part 1 when NRG fell down, suggesting that this version of the containment suit can be opened more easily.
It is shown in The Rooters of All Evil, that different variations of the containment suit exist.
The only known object that can penetrate the containment suits is Taydenite.
