Stuck in the lost river

When i was going to the lost river, let my cyclops into the entrace and went with the prawn gather some nickel ,when i came back to the cyclops ,he was discharged ,because i let the discreet mode on for too long, i though i would have to come back to the surface take some cells and come back, but i just build a base a little lower where i put a thermogenerator and made an energy cell recharger ,if you're pass by this problem remember that post ;) (oh, and i got some bulbo trees on my cyclops)
