Anita's Friend-ly Zoo combines lovely bricks from Friends sets with others across the LEGO spectrum.
A fun little zoo tram runs around on LEGO train tracks. System bricks from other themes all blend seamlessly. She incorporates animals from DUPLO and other systems sets (such as Prince of Persia's Ostriches), plus many LEGO Friends animals too. They go together just like the alphabet: A-to-Z(oo)!
Here's another angle view. She built it as modules, to allow it to grow and be re-arranged.
And the sign with a very clever use of those Friends life-preservers!
There should be a smile on your face now! :-)
