'follow' item when held will cause mob to follow player, can be single string "default:apple" or table {"default:apple", "default:diamond"}
'view_range' the range in that the monster will see the playerand follow him
'walk_chance' chance of mob walking around
'jump_chance' chance of mob jumping around, set above to 0 for jumping mob only
'walk_chance' chance of mob walking around, set above to 0 for jumping mob only
'walk_velocity' the velocity when the monster is walking around
'run_velocity' the velocity when the monster is attacking a player
'runaway' when true mob will turn and run away when punched
'stepheight' minimum node height mob can walk onto without jumping (default: 0.6)
'jump' can mob jump, true or false
'jump_height' height mob can jump, default is 6
'jump_height' height mob can jump, default is 6 (0 to disable jump)
'fly' can mob fly, true or false (used for swimming mobs also)
'fly_in' node name that mob flys inside, e.g "air", "default:water_source" for fish
'damage' the damage per second
