"fingernails as long as those of Struwwelpeter"

Struwwelpeter, or 'Shock Headed Peter', is a character in a German book of cautionary tales for children (1845) by Heinrich Hoffman (1809-1894).  The tales warn of the dangers of thumb sucking, fidgeting at table and racism, with the title character described as a sloven; 'See! His nails are never cut; They are grim'd as black as soot; And the sloven, I declare, never once has comb'd his hair.'
