Very few Invizimals live in caves. They prefer open spaces. But only one Invizimal, we know, actually lives in a hole! Yes, it Vipera, a horrible creature that digs his hole at birth and hidden there throughout their life. Lazy and rude, Vipera never strays too far from his lair, where he becomes perceived as problems.
How to capture Edit
Call him and when he comes out of a hole you crush him hard. Repeat the process until you capture it.
