A small adolescent child with an amazing fear of large burly men that carry chainsaws at Halloween Horror Nights. He also tends to fear most things larger than him. Including Micheal Myers from the Halloween Series.
1) Roberto was so scared by the Chainsaw Drill Team that he attached himself to a tree.

2) Roberto pissed himself when he saw Micheal Myers outside his window.
