SB 10.11.7

gopībhiḥ stobhito ’nṛtyad
 bhagavān bālavat kvacit
udgāyati kvacin mugdhas
 tad-vaśo dāru-yantravat
Word for word: 
gopībhiḥ — by the gopīs (by flattery and offers of prizes); stobhitaḥ — encouraged, induced; anṛtyat — the small Kṛṣṇa danced; bhagavān — although He was the Supreme Personality of Godhead; bāla-vat — exactly like a human child; kvacit — sometimes; udgāyati — He would sing very loudly; kvacit — sometimes; mugdhaḥ — being amazed; tat-vaśaḥ — under their control; dāru-yantra-vat — like a wooden doll.
Translation: 
The gopīs would say, “If You dance, my dear Kṛṣṇa, then I shall give You half a sweetmeat.” By saying these words or by clapping their hands, all the gopīs encouraged Kṛṣṇa in different ways. At such times, although He was the supremely powerful Personality of Godhead, He would smile and dance according to their desire, as if He were a wooden doll in their hands. Sometimes He would sing very loudly, at their bidding. In this way, Kṛṣṇa came completely under the control of the gopīs.
