No, Albus needed no help, but instead of saying so, he gave Jaune another slight smile and replied, "You can guide him toward the cage if he gets off course." Just in case, he added, "Or her."
Yogies should do the trick. Albus placed a trail of the small treats from the middle of the kitchen counter to the now open mouse transporter. In the transporter itself, he placed a small pile of them to keep the mouse there until he could close it. Satisfied with it, Albus moved back so the mouse would feel more encouraged to come out and see what had been offered to it.
