Hello Elena :) "Putong" means precisely 'plop' ,the characteristic sound made by an object dropping into water without a splash. 'A frog plopping into the pond' is a good example of such a sound. P.S It is " 扑通" in Hanzi , while "普通" means common, ordinary .

hi pu tong 扑通 is an onomatopoeic word it imitates the sound of a thing or an action. jump 跳tiao4 is verb. :)

pu tong = 噗通 I guess that what you mean. =) ah....it is a sounds. when you jump into water. *pu tong* tiao = jump, hop (correct) I hope help you more. but my english is not very well.

一只青蛙,一张嘴 两只眼睛，四条腿。 铺通，跳下水。 找到了在一本书

maybe theres other meaning. pu tong 普通 ordinary
