Everyone loves llamas. There are so many kids books staring llamas. I think we just love saying "llama". My favorites are "Is Your Mama A Llama" (which seems to be out of print or at least out of stock at Amazon). More current is Anna Dewdney's "Llama, Llama" picture books. "Llama, Llama Red Pajama", "Llama Llama Misses Momma", "Llama Llama Mad at Momma", "Llama Llama Holiday Drama". The third littlest Best Loved Grandbaby loves to quote from these extensively.
The other new animal if a Giant African Anteater - or an Ardvark if you prefer.
