I think there should be a new tier 3 boss in the clockworks. They should make King Tinkinzar and the Crimson order plus an extra room full of gremlins for a gate, plus some mechas because the gremlins made them. That would be a really good idea in my opinion.
New Tier 3 Boss
I think the first floor should be gremlins and mecha knights. There should be missiles and some unreachable gun puppys. The only way to destroy them is to trigger a switch, so that they self destruct. the second floor should have gremlins and lumbers/scuttlebots. On the boss battle of this floor, the crimson order comes, they should be x4 the strength and defense of the regular gremlins. They should have 2 gremlin healers. The more you defeat the easier it is to kill the rest. Then the boss should have 2 holes on either side of him, repeatedly summoning gremlins and mecha knights, that when defeated drop hearts and capsules. When Tinkinzar is defeated, there should be a 8x5 row of red treasureboxes and 18 gold coins. Thank You for your concern.

Many times suggested, and I put mine up to show just how. Anyways, what makes your idea unique, as in what view do you have on the Tinkinzar boss battle? Please, describe your boss battle because this was suggested many times, just so it would look like you invented your own boss battle instead of just saying it and leave.
