For players with limited funds who don't badly need the space, I suggest you skip whichever plots you can to find a shortcut to the Leopard. Maybe you can put some Electric drones to work on cheap Fire habitats.
Also, if you're able to reach your maximum number, max out your habitat limit BEFORE you expand to the Lightning Leopard. It will give you an extra habitat over your limit. But this will only help if you're prepared to work with just one Electric habitat. If you have 32/31 habitats (the free Electric Expanse being the 32nd one), and want to add Electrics or swap out habitats, you will have to sell TWO habitats in order to build any other. If you sell just one, it will put you back to 31 habitats and you won't be able to buy another one because 31 is your true limit. LOL. We can't win.
