Lumbar Nook

The Lumbar Nook is an area in Bowser's back, and is the smallest area in his body. Mario, Luigi, and Starlow go here, due to a complaint from Bowser. Here they find Toadsworth, who was sitting there doing nothing. They tell Toadsworth of Bowser's back pain, and Toadsworth jabs his stick into a soft part, but it causes no effect. Mario and Luigi then drill into the soft part, when Toadbert comes to Toadsworth and sits down for tea. The plumbers pop out of the tissue, and Bowser learns how to use Spike Ball.
