Pearled Crab King should drop extra Message in a Bottles

[Pumking7]

It appears that in game pearled Crab King is supposed to be a more difficult version of Crab King, akin to Toadstool/Misery Toadstool, for the more difficult form has better loot in the form of the mandatory questline item, The Celestial Tribute. However after defeating Crab King in his pearled state there's no real reason to fight him again at this difficulty (using 3 opal gems for future fights). The only other reason to fight him in his Pearled form is for a alternative winter's feast adornment specific to Pearled Crab King. 

Players should be rewarded for repeating a more difficult version of Crab King so why not let him drop extra message in a bottles. At the moment Crab King drops 2 bottles guaranteed on defeat and a chance for an extra 2 with each having their own 50% chance of dropping (to which a minimum of 2 bottles is a bit low for a boss fight). Pearled Crab King should have 2 extra bottles added to his guaranteed bottles loot pool. If this were the case then I could see Crab King being a valuable refight for 4 bottles would be a great reward for challenging the player to a more difficult battle.

I'd go as far to suggest that there should be +1 bottle for every 3 opal gems. Would love to see more challenge = more reward with CK.
