Gaming Need help with Bokura wa Kaseki Holder

[NeonEclipse]

My girlfriend has been playing through this game and has now come to a point where she cannot advance any further in the game (this is probably because neither of us can read japanese) and we cannot find anything online that tells us how to progress in the game. As such I would be very grateful if someone here could translate what the screenshots I have linked to say as we believe that one of them is telling us what we need to do to advance through the game.

Many thanks to anyone who can help us

EDIT: Okay we've managed to find someone who was able to help us solve the problem, but thanks to anyone here who could have helped us. For anyone interested the man in the junk shop was telling us that he'd only help us if we had a Dinosaur called ???? on our team, so once we had one of them he then allowed us to battle him and upon his defeat gave us something that we could give to the moleman in the mines, which then allowed us to progress through the game.
