Winnie-the-pooh: piglet meets a heffalump (HarperCollins Publishers)

"Oh, dear, oh, dear, oh, dear!" said Piglet to himself. And he wanted to run away. But somehow having got so near, he felt that he must just see what a Heffalump was like. Pooh and Piglet decide to catch a Heffalump together, but when Piglet meets one in the middle of the night, he realises that catching Heffalumps is much easier with two.
