Creep Mouse is an informal game played with babies.[1] In the game, one (child, teenager, or adult) marching his or her two fingers up from the infant's toes towards the baby's midsection, reciting a rhythmic verse something like “Here, comes, the, creep, mouse, from, the, barn, into, the, house” once the walking fingers reach the midsection, the baby is then tickled[2] and the sounds “giddy giddy getchya” are made, much to the baby's amusement.[3] This game is often repeated with an increased cadence with each round.
In the United Kingdom, this game is played along to the song Round and round the garden.
