Lin Mu helped Little Shrubby gain better control of the hand for a few hours before he was finally able to use it. Though controlling the fingers was still hard for little shrubby as it had never used them before.
For Lin Mu or anyone that had a human like hand, it would have been easy to control them as they were used to it. But for a beast like little Shrubby, it had never done the same and as such, it was hard for it to learn.
It would be the same for humans if they were given an appendage they were not familiar with. For example, if a tail was given to Lin Mu he would have a hard time learning to use it too.
It took the entire night, before Little Shrubby was able to gain a basic ability to move the fingers. Its grip was either so strong that he snapped the utensils when he tried to hold on to them, or so weak that they simply fell from the hand.
