How to make a trail for a character

i made a character in a game i’m working on, and he is a snail, but i don’t know how to make a trail follow behind him when he moves around. the trail is supposed to be on the ground, and made of slime. this is an example of how i want it to look:

Try checking when the player moves itll clone a slime template and put it underneath the snail. You can use CFrame.new(Snail.X, Snail.Y - 0.5, Snail.Z) or make a part right underneath the snail. (I recommend using that one)
