 Creatures that do not fit the classic bird or yamabushi image are sometimes called tengu . For example , tengu in the guise of wood @-@ spirits may be called <unk> ( occasionally written <unk> ) ( <unk> , dog guests ) , but this word can also refer to tengu with canine mouths or other features . The people of Kōchi Prefecture on Shikoku believe in a creature called <unk> or <unk> ( <unk> , <unk> , lawn tengu ) , but this is a small childlike being who loves <unk> wrestling and sometimes dwells in the water , and is generally considered one of the many kinds of kappa . Another water @-@ dwelling tengu is the <unk> ( <unk> , river tengu ) of the Greater Tokyo Area . This creature is rarely seen , but it is believed to create strange fireballs and be a nuisance to fishermen .
