Blot and Og's Monster Party

Blot and Og are sending out invitations for the biggest ever birthday party in the
history of Blogsville.
They spend a while imagining what sort of guests they might have at this party –
there will certainly be Whojammacallits and Widjamafoos zooming round on the
clouds playing Koogabazoos! But Blot and Og are completely unprepared for the
arrival of real guests. And when dozens of creatures suddenly turn up they don’t know
what to do! Will the guests be disappointed when they see what’s on offer in
Blogsville? Or will this turn out to be the best party in the Universe after all?
