So there absolutely had to be a frog!
I have found that when I read Haicooo to kids, the poem about the frog kissing, the kids burst into giggles...apparently kissing a frog is the highest level of comedy to a 5 year old.
Frogue is a French frog
He is very romantic
He likes to kiss you
Personally, I think if you go around kissing frogs, you might need to contact infection control...
