An instant classic story book combining the perennial appeal of diggers and behind the scenes life in a zoo! Renowned illustrator Brendan Kearney makes his debut for Lake Press following bestselling success with The Adventures of Finn and Skip. It's an exciting day at the Little Rubble zoo, as work is beginning on a new reptile enclosure! The only problem is that it has rained all week and Mayor Digby's digger soon becomes completely stuck in the squishy mud! There's only one thing for it - they need a bigger digger! But neither Zookeeper Alice's digger nor Builder Bill's digger manage the job - and before long all three diggers are stuck! Thank goodness for Rosie Brown, who brings in her humungous digger. Will her digger save the day?
