Karna and Eklavaya both were looking at the little fox who just ate the whole apple which Eklavya was using as a target practice, While the fox just lay there without any shame.
A moment before Karna came to the guest palace area and was searching for Eklavaya as his heart felt anxious for no reason at all, So he thought there was something wrong with Eklavay and searched for him.
He found him here in the guest garden practising archery with the makeshift bow and arrow on the apple, Though he wanted to use something else but soldiers informed him that they don't have anything else for target practice.
But they said not to worry about wasting food as these fruits will be fed to the horses and others at the end of practice, So Eklavya decided to use it and put the apple on the rock and go far in his position and then aimed at the apple.
