"The Foggiest Notion"
Back at venerable Ireland Yard, Batman receives an exploding package containing three silver bells, and he recalls a pub called The Three Bells is somewhere in the city. They investigate, but the under-age Robin has to wait outside while Batman enters to find Lord Ffogg and his highwaymen waiting for him.
Back outside, the young girls from Ffogg's finishing school mob Robin and easily carry him off, being a gentleman he could hardly defend himself. Batgirl is also captured and paralyzed while investigating Lord Ffogg's secret Cricket Pavilion, where he keeps all his booty.
It's hard to understand how Barbara has kept her other identity a secret all this time. When she goes travelling, she brings her Batgirl costume in a suitcase clearly marked with the Batgirl ensignia on the side.
