"Why yes. This one is available. You seem like a kid with a good eye. Here you go." Handing the boy the sphere upon touching it the wrong creature would escape. Laughing a bit he looked at the boy with a sheepish grin. "Apologies wrong one, my eyes need fixing I suppose." The Ball tailed cat looked at its new owner with cold eyes before licking itself and getting a sniff of its new surroundings.

He handed the boy the correct orb now. Once the boy touched it the reptile would appear in a dazzling light next to him. "That there is a Fire Lizard. Most monsters don't like fire so its a good choice from the get go." He looked at the boys suspicious looks. "I think that would be enough for you. If you want another go find one in the wild. What you will need is simple. These stones." He showed the boy the glowing crystal rock. "These have soul essence inside. These take forever to mine but are worth it. Certain monsters love these. Besides that I hope you can hold out from eating prime foods because you'll need'em to gain a monster's trust."

He stepped over and grabbed a drink from his table. He stepped back out whilst sipping his cup. "Gaining a monsters trust is tricky no doubt. The rarer the beast the harder to get to want to follow you. Sometimes you have to use aggression, knocking it out and recovering it to health will be the only way for some monsters." He sighed and finished his drink. Tossing it behind him after.

"So. With the monsters you have you can only do so much. They will listen to you to an extent but they know only a handful of attacks. If you want more out of them you'll need to train them and feed them healthy meals. You can also use certain items to boost them. Tons of them exist like herbs, mushrooms, or something practical like armor. I'm sure you'll get enough funds to get what you need soon enough." 

After saying all this he looked at the crowd. Raising his arms he shouted. "Whose next?"
