Little Minnie Snodgrass climbed into the bucket when her mum Gemma was mopping the kitchen floor.
But when the 29-year-old from Conisborough, South Yorkshire tried to lift her out, she realised her 16-month-old daughter was stuck fast.
Gemma's mum, Rose Cope, drove the pair to hospital while Gemma kept an eye on her mischievous girl in the back of the car.
However, once they arrived, doctors had to call in the fire brigade, who managed to free her with bolt cutters.
Thankfully the tearaway toddler was unfazed by her ordeal.
Gemma said: "Minnie looked quite content as she sat waving her arms and dancing in the bucket.
"She barely let out a whimper the whole time. She actually seemed to enjoy being stuck and was dancing around in the back of the car."
A South Yorkshire Fire Service spokesperson said: "If we weren't here to rescue toddlers from mop buckets, who would? It's another example of the vast range of work the modern fire and rescue service is called to respond to and which the public rely on us for."
