The Land of Walking Through Cake

Meri, the Tackling Dummy, Wut, and Jethro discover the monkeybars and travel on it to The Land of Lavender Thought. Wut is swinging below. The dummies who live there have just finished decorating a spectacular enormous cake. If you're standing near a delicious beautifully decorated cake larger than your house, and you wonder how many layers it has, what do you do? Why, jump in from above, of course, and count the layers as you fall through.
"Falling through the cake's immensity, through layer after layer, down, down, down, down, easily floating through sections of icing and then of cake, one after another, Meri counted the layers as she passed: '33-34-35-36...'And finally, approaching the round base, she fell right into the Tackling Dummy's arms."
To get to The Land of Pink Windmills, where The Tree of Ticket Leaves now grows, they must cross The Land of The Yellow Trampoline. It's a whole land, beautifully yellow. And they must bounce across it---even Jethro, the huge Buffalo Unicorn! And Wut, the question mark, who already bounces anyway! But first, Wut has a big surprise! It's not small.
Slipping down The Sliding Board over a mile long to The Land of Pink Windmills below, they suddenly see huge fireballs, colorful suns, start rolling down behind them from the cliffs above. The gigantic fireballs roll faster than Meri and the Tackling Dummy can slide! There seems to be no way they can be saved!
