What is the 'Outside"?

Toro didn't like walking on grass eventhough there were birds on it. I think the grass bit was too open for him. I tried twice but finally allowed him to go about walking very close to the walls and to peek out at the outside from behind them. The drainage holes acted as a walking track for him and everytime someone passed by, he crouched in it, making himself smaller :)

Here he was very interested to know what was happening outside when he finally took courage and actually walked out from behind the wall. He stood there for a few minutes before retreating. I think he is a brave little thing :)
