It's only now I have redeemed my childhood by watching Hayao Miyazaki films in the 20 years of my life!
Due to limited space I couldn't include all the Ghibli critters like the beloved catbus or haku's dragon form, the laputa robot etc.
Turnip Head | Heen | Calcifer from Howls Moving Castle
Mouse & Bird | No Face from Spirited Away
Ponyo (fish form) from Ponyo
Jiji from Kiki's Delivery Service
The Totoro's | Black Soots from My Neighbor Totoro
Kodamas from Princess Mononoke
Teto from Nausicaa of the Valley of the Wind
All characters trademark of Hayao Miyazaki & Studio Ghibli
Also, did you know that Miyazaki did a lot of films which are not Studio Ghibli? His Puss in Boots was really cute and his Lupin the Third: The Castle of Cagliostro was good too. You can also buy the original Nausicaa of the Valley of the Wind comics which were all hand drawn by him. They are beautiful!!
