Yakari - Volume 10 - The river of forgetfulness

While trying to save a bear cub from drowning, Yakari falls into the river and
hits his head on a rock. By the time he washes ashore and is found by a
distraught bear mother, he has forgotten who he is. The she-bear is convinced
that he is her son, turned into a human by the Bear Spirit, and begins to
train him for his new life. Can Yakari’s friends find him before he disappears
into his new world for good?
