当五个朋友尝试找出是谁在晚上发出声音的时候，想象力就信马由缰了……

乌龟和它的朋友们在吊床上很快就睡着了。突然，乌龟醒过来，低声问道：“你们听见声音了吗？”于是，一个有些小曲折的侦探故事开始了。谁在发出声音？吊床上的动物们——乌龟、蝙蝠、章鱼、小鸟和山羊——就随自己的想象力信马由缰。是一只巨大的蝙蝠吗？或者一只嘴很大的鸟？也许是有点像乌龟，有点像蝙蝠、有点像章鱼、又像鸟的雄山羊？

猜了好多好多之后，才发觉原来是一只友好的大象。这些小动物们邀请大象也睡到他们的吊床上，很快，新一轮有关是谁在晚上发出声音的疯狂猜想又开始了。Imaginations run wild as five friends try to find out who is making night noises...

Turtle and friends are fast asleep in their hammock. Suddenly, Turtle wakes up and whispers, ‘Do you hear what I hear?’ And so begins a detective tale with a twist. Who’s making the noise? The animals in the hammock – Turtle, Bat, Octopus, Bird and Goat – let their imaginations run riot. Is it a giant bat? Or a bird with a huge beak? Perhaps it’s a tur - bat - octo - bird - billy?

After much guessing, it turns out to be a friendly elephant. The animals invite Elephant to join them in their hammock and soon new wild imaginings about the night noises begin all over again.
