It's not carlsnaut and boost ingram, it would have to be hylash and boost ingram.And the reason Wired and Altair can combine without a peg is because they are both marbles, they only need a peg if it's a trap and a marble.
Yea… The only way I can figure out how is to put the real ingram's tail up through hylash's body and snap the tail down… But that doesn't really to it…
To make the tail not get stuck you don't put the part where it turns through. Again, this may not be right, but then again the first Meta Altair wasn't. But if this one is… COOL!
