...become so small I could crawl between Saburo's paws to sleep.

Does anyone remember:
"First I shut my eyes real tight, then I wish with all my might! Magic words of poof, poof, piffles, make me just as small as Sniffles!"

"Mary Jane and Sniffles" from "Looney Tunes & Merrie Melodies Comics"; Warner Bros.

I like the Finnish version better:"Silmät suljen lujasti ja toivon oikein kovasti. Taikasanat tokka tikko, tulen pieneksi kuin Mikko".
Yay, I've learnned bit of Finnish language )
