Loggo

Loggo is a talking toilet that appears in a few Banjo-Kazooie games. He claims that he was owned by Gruntilda.

"I can't believe you went down there! Wash your hands now, filthy bear!"

In Banjo-Kazooie Loggo is found in the bathroom of Mad Monster Mansion. If Banjo transforms into a pumpkin transformation, Loggo offers to flush him down into a septic tank with a few Whipcracks and a Jiggy. If the correct Sandcastle cheat is entered, the Green Mystery Egg can be found on top of Loggo.

Banjo-Tooie
In Banjo-Tooie Loggo is located in Grunty Industries. When Banjo and Kazooie first encounter Loggo, he complains that he is clogged up. Kazooie can use Bill Drill inside his toilet bowl to get a dirty Cheato Page that is plugging his pipes.

If Banjo and Kazooie talk to Loggo a second time before getting him unclogged, Kazooie mentions that he should call a plumber. Loggo says that he does not think Mario does such work anymore. In the Xbox Live Arcade port, the line was altered to say "Italian plumber" instead.

"In Mad Monster Mansion, Banjo couldn't fit down Loggo until he became a pumpkin. In Grunty Industries, Kazooie used her beak to unblock him. Now Loggo's charms are replicated here in full size."

In Banjo-Kazooie: Nuts & Bolts, a giant replica of Loggo appears as an exhibit in Banjoland. The U-Bend must be filled with sheep, and it later serves as the hole in Mr. Fit's golf game.
