Love doing monkey TF. Here's a  Little Sorcerer reward for Trétoile

2 half-twins are on their room alone trying out their new toys,  a pair of staffs with a monkey figurine sitting on its top. The 2 kids gained monkey-like agility and a monkey tail from holding their staff, the boy is worried about these changes while the girl is having a blast about it.
