Redhawk Caldera he who has gas travels at the back of the pack

While his brother was very interested in his surroundings and busy with playing a leader, Peter was more focused on following him and did not look around much. He wore a happy smile and ambled along, feeling glad that there was something to do. Now and then he would stop and look Ferret's figure that was moving away at a quick pace, hoping to draw his attention, but this did not happen, therefore with another "eep" Peter caught up with the engine. 

When Ferret came to a halt abruptly, the little boy almost crashed in him, stopping himself only mere inch away. His brother plopped down on the belly and began to move in a very odd way. "Uhh?" he formed his confusion in a single syllable. When no answer came, he decided that perhaps this was a game. And with a loud "EEEEEPPPP!" he pounced at his brother and probably scared the bird away.
