#
# ~ Adding Trailing Character:
# <game_character>.add_trailing_character(<name>, <hue>)
#
# ~ Deleting Trailing Character at a index
# <game_character>.delete_trailing_character(<index>)
#
# ~ Delete Last Trailing Character
# <game_character>.pop_trailing_character
#
# ~ Get Last Trailing Character
# <game_character>.last_trailing_character
#
# ~ Get Number of Trailing Characters
# <game_character>.number_of_trailing_characters
#
# * For Events, Replace <game_character> with
