The images below can be connected by a single word.
What is the word and what are the connections?
I think the word is:
The connections are:
Hoodie – Hood + IE, Internet Explorer, that is
Neighbourhood – Flanders is the Simpsons' neighbour.
Boyz n the Hood
Little Red Riding Hood
Hood ornament – on a car's radiator ✽
Robin Hood – the figure is of Batman's sidekick Robin
As for the title:
A hood (a gangster or rough person) might be a toughie.
✽ Thanks to the many helpful commenters who pointed me into the right direction on the connection to the hanging Harry Potter Christmas-tree decoration (8).
