Trivia

• With Tack Awesomizer activated, the piles of spikes the factory produces will have 20 spikes in it.
  • This is slightly better than a Spiked Ball Factory without Tack Awesomizer in terms of the popping power, only by 4.
• Following a Version 22.0 nerf for Bigger Stacks in BTD6, the cost of Bigger Stacks has always increased by $100 with each generation of BTD games.
