My shoulders are shaking whilst I sit at my desk laughing at all the bunny song re-writes! 
ablative- I actually like the gruffalo fish, sorry
but the 'squeaking' rabbit, yes
smartypants I love making up tunes to singing bits- they are a permanent feature in our household, particularly the one in 'smartest giant', but also bits of tabby mctat (the brass band), and tiger who came to tea ('Goodbye, goodbye, goodbye').
psychicsatsuma - your name is fantastic! Snail and the whale is a little worthy, but I like the tale of the snails trying to better themselves... puts me in mind of ordinary working people in the late 19th/early 20th who were always marvellously well-read and accomplished in Art, performing arts, horticulture, or artisanal woodwork, despite having to work 10-12 hours a day, and not having a spare farthing, but always trying to improve themselves.
