creeping

a slow mode of locomotion on hands and knees or dragging the body

a crawl was all that the injured man could manage

move slowly; in the case of people or animals with the body near the ground

The crocodile was crawling along the riverbed

to go stealthily or furtively

..stead of sneaking around spying on the neighbor's house

grow or spread, often in such a way as to cover (a surface)

ivy crept over the walls of the university buildings

show submission or fear
