To show you how impossible der savants of Europe dink such a ding mighdt be, dey haf sendt me to find such a creature or proof positive dot dey still are living members of der animal kingdom. Dot vos de treasure I vos sendt to findt! A treasure dot dwarfs into insicnificance any mere tiamonts or goldt!”
