Exploring outside the cage

After Udon's 1st steps out of the cage yesterday. He (I found out that he is a male) has the desire to go out. So I let him out a while and he ran to my TV console trying to bite it.

I quickly put him back to his cage. Udon kept looking outside when he was in the cage.

Then I remember that I had borrowed a hamster ball from my bro. Udon walked into the ball and loves running inside. I tried to let him out of the ball a few times but he dun want to come out until he was very tired.
