I've been thinking about a couple of turtle equipables that might be interesting - for example: Electro-magnet - expends 1 fuel, gathers all item entities in a radius around the turtle, and what about a tank - allow the turtle to store fluids by extracting from a bucket - could be used to fuel the turtle directly or to refill a bucket

nice ideias, could be very interresting
