Bagpuss in the version I heard he was supposed to have lost it 'down the cundie'. ? does anyone know this - does 'cundie' equate with 'netty' both meaning drain (the big square ones in the gutters at side of roads).

I thought it was 'condie' (from 'conduit') - that's the version I learnt ages ago, form a Geordie!

(Yes, 'netty' = toilet as Bagpuss says.)
