Woops didnt see this before I posted lol. Do exactly what is said here ^^The green on the leg is bruising. The bumblefoot on the toe looks more serious than on the footpad. You can soak his feet and legs in some warm Epsom salts water. Then you could try to remove the bumblefoot scab and try to get any pus or plug out of it. Apply a gauze pad after applying some plain Neosporin or Triple Antibiotic Ointment and wrap the foot with vet wrap, but not too tight. Check that the circulation is good. Then I would rub some vaseline up and into the leg scales to smother any mites.
