The title's a little....hard to pronounce, heh. Pity the man who tries to recommend your poem to his friend! Hey, head over to ABCtales and check out Macjoyce's de...do-do da-da-di... never mind.
I like the idea behind this poem a lot. The ABAB rhyming scheme was used well throughout. (I wonder how many more words rhyme with dodo?)
I also enjoyed the mammoth... 'Devious woollen runt'... i'll never look at a mammoth in the same way again.
Two tiny suggestions:
Or other such Flintstonian stunt
--could be Flinstonian stuntS, with an s at the end? or maybe 'Or some other Flintstonian stunt'
The word 'dodo' just begs for a little alliterative play. You did that in your title... but is there any way that could be worked into the poem? It doesn't need to of course...but it would be fun ^^.
