1st off, these canals will require a whole lot of hitbox defining. The more complicated system, the more work for the modder and I know making hitboxes is most difficult.
Anyway, imo there are way too few places in disco, where only a fighter can get. Only ones I know is that nomad lair (whatever happend to it) and inside the Hispania.
Now for the mokeys. Imo, monkeys should live on a jungle-like world. Kinda natural for them despite them all wearing monkey suits (I bet this alusion was made on purpose ingame). Planet of the apes...
Honestly, with one or two nomad fleets flying around these planets I can hardly belive that the entities living on Gammu and Primus joined the nomads to survive.
