yes his body and age don't match jiraya's, even his face marks are slightly different from jiraya's at young age

well, he could be his never mentioned son, his long lost brother, his modified clone. as for his toad it could be totally unrelated to mount myoboku (it doesn't seem a normal toad),he also sacrificed a toad to initiate katon on konohamaru, gamabunta wouldn't let one of his (children) die like that i suppose
