The Ebublio Jinx (Ebublio) is a jinx that entraps the targeted witch or wizard, or indeed any target, in a very large bubble that cannot be popped by physical force.
It appears as a brilliant purple jet of light accompanied by purple flame and smoke. It is useful when fighting Dugbogs and Erklings.
This jinx could be bought at Wiseacre's Wizarding Equipment in Diagon Alley from at least 1991 to 1997, but most likely in years previous and thereafter.
