A tonttu is a small, typically shorter than half a meter tall, or even as tiny as a thumb, bearded fellow with a pointy hat. They often have a stout and slightly chubby physique, often portrayed as mischievous and whimsical in nature.

Their pointed hats are often red or green, and can have a bell or tassel hanging from the tip. Tonttus are known for their wrinkled faces, rosy cheeks, and bright, twinkling eyes that convey a sense of curiosity and playfulness. They are often depicted wearing traditional clothing, such as a tunic or vest, and sometimes seen carrying a walking stick or lantern.

So if you see those so-called "gnome" statues somewhere, that's sometimes what a tonttu might look like. Tonttus however are not gnomes.
