Spider-Man Family #6

Synopsis

Thor saves a woman from being mugged and, when she kisses him as a reward, he is transformed into a frog by his evil brother, Loki. Peter arrives late for class and finds that he has to dissect a frog. When the frog breaks his glass killing jar, Peter knows something is up and Spider-Man takes the frog back to Central Park. Recovering his hammer, the frog becomes Thor, Frog of Thunder and he and Spider-Man return to face down Loki and break the curse (with a little kiss from Mary Jane to boot).
