I second the wonderful Hyacinth Hippo! She is my favorite anyway!
Here is a little history on her:
"Hyacinth Hippo was the prima ballerina of the famous dancing hippos in Walt Disney's Fantasia (1940). The hippos appeared along with troupes of ostriches, elephants, and alligators in a hilarious and inspired parody of classical ballet, set to Ponchielli's "Dance of the Hours." The action takes place in a Great Hall of fountains, gardens, and marble columns. Each group of animal dancers represents a particular time of day. First come the ostriches (Morning), followed by the hippos (Afternoon), the elephants (Evening), and finally the alligators (Night). Hyacinth is the real star of the piece, for she does not depart with the rest of her entourage but remains, asleep, through the elephants' dance and is the first living thing encountered by the alligators. The highlight of the sequence begins when Ben Ali Gator, the leader of the alligator troupe, sets his lecherous eyes on the dozing behemoth in the transparent tutu and immediately falls in love with her. The pas de deux between the rotund Hyacinth and the wiry Ben Ali is a milestone in the history of character animation.
Hyacinth herself was modelled after Tatiana Riabouchinska of the Ballet Russe. (Animators also studied live-action footage of actresses Hattie Noel and Marjorie Babbitt.) Reportedly, Ms. Riabouchinska was delighted with the results. What makes Hyacinth so appealing is that, even though she is huge and ponderous, her graceful movements and coy expressions make it obvious that she considers herself dainty and petite."
Or, even some ideas as to some of the more obscure characters...I could try to squeeze into. Any help would be great.
