Sid wanted to find those specially made shorts similar to what Linc has on. They actually make special clothes for reptiles for certain sizes of tails and leg gaps. Sid actually has about an 8 and 1/2 in gap between his legs and Linc has about 7 inches. So they make pants or shorts that go from 4 inch gap to about 9 and 1/2 inches. It goes 4, 4 & 1/2 5, 5 and 1/2 inches and it goes up every 1/2 inch till 9 and 1/2 inches.

Considering he's a lizard and so clothes on a reptile is basically optional, and they don't need dressing rooms, but often they do like to wear stuff to help out with character and personality.
