Electro Blooper is a Blooper from Paper Mario. Living in Toad Town Tunnels, Electro Blooper is the second Blooper Mario encounters during the events of the game, following the regular Blooper, and is succeeded by the Super Blooper. To get to the Blooper, Mario can either defeat the Blooper east of the entrance, then go west of the entrance, or vice versa, or use the spin-jump from Boo's Mansion, then use Sushie's ability to swim to the other side and start the battle. The squid enemy guards either a Shrink Stomp Badge, the First Floor Warp Pipes, or the Lavalava Island Warp Pipe. Electro Blooper differs from normal Bloopers; it is bigger and more powerful than others of its species. Also, this creature has an electric charge, preventing contact with it. During this state, Mario and co. must use a move that does not attack it directly, like Parakarry's Shell Shot. After a long battle, Mario and co. manage to beat Electro Blooper and advance further into the tunnels.
This is the only Blooper boss in the game where partners cannot be switched before battle upon reaching the other side, which is dependent on where Mario is fighting it.
Unlike most electrified enemies, when hit with any attack, the electricity will discharge while enemies keep the status for a few turns or until their health reaches 0.
