Spikes R Us

Spikes R Us is a Specialty Building for the Spike Factory added in an update to Bloons Tower Defense 5 on the 21st of June, 2012. It costs 500 to purchase and it increases the cost of Tack Towers by 5%, whilst decreasing the cost of spike factories by 5%. It can be upgraded to increase the lifespan of spike factory spikes by 10%, and it can be upgraded to generate a free road spike pile for every round. This building is very useful as it lowers the cost of Spiked Mines, and since Tack Shooters are not overly expensive, the disadvantage doesn't overcome the advantages. A 10% increase of the lifespan of Spike Factory spikes is helpful when the Spike Factory is used as an exit defender.

Upgrades[]

Initial cost is 500
Second upgrade costs 500
Third upgrade costs 1250 (1000 in the Mobile version)
(Bloons TD 5 Mobile only) Fourth upgrade costs 1200 (all Spikes and Balls pop 50% more Bloons)
Disadvantage (while the specialty building is active) increases the cost of Tack Towers and their upgrades by 5%

Trivia[]

Spikes R Us is a play on the real store named Toys "R" Us.
- In Toys "R" Us you can buy toys, so this is a place to buy Road Spikes, as the name is Spikes R Us.
For the third upgrade, you will still get free road spikes every round, even if you don't have any Spike factories.
This is the only specialty building that gives you something that is not completely related to the towers themselves. (Road spikes are not Spike Factories, but they probably come from Spikes R Us.)
This is one of the few Specialty Buildings where it costs 500 to purchase to building. The others are the Dart Training Facility and Tack Research Center.
Despite the fact that Tier-2 of Spikes R Us mentions the lifespan of Spike Factory spikes, it also affects the lifespans of balls and mines from the Spiked Ball Factory and Spiked Mines upgrades.
- This is because even though the Spiked Balls are technically not spike piles, they are Spike Factory projectiles, so they are affected.
Free Road Spike piles provided by the Specialty Building last only for the current game.
- Free Spike Piles provided by ways other than the Specialty Building (which is only possible in BTD5 Mobile) do not get used up when this Specialty Building is activated unless all Road Spike piles provided by the Specialty Building are used up.
