Healthy Bananas (BTD6)

Healthy Bananas is a Support Monkey Knowledge point in Bloons TD 6, added in Version 15.0. It allows all Marketplaces to gain +1 life after every round, and Central Markets gain +3 lives per round, but Monkey Wall Street gains the same amount of lives. It requires eight support knowledge points invested, Inland Revenue Streams, and a one-time purchase of 500.

Summary
Gaining more lives early on the game allows for better survival in later rounds. The most valuable part of this MK comes from its vital life regeneration without needing to spend expensive upgrades such as Support Chinook or Spirit of the Forest.

Tips

 * Lych boss events are where this MK will shine the best, as Lych-Soul's life draining is highly damaging for player defenses and, most importantly, Lych-Soul can kill the player instantly down to 0.
 * This is especially the case with Elite Lych Tier 1. Tier 1 Elite Lych-Soul drains a whopping 11 lives every time it inflicts a health loss onto the player. As most Elite Lych events start with 50 lives, having even just a few Marketplaces are capable of at least doubling the total life count, resulting in a much larger health cushion.

Trivia

 * The Healthy Bananas MK in BTD6 is far weaker than in BTD5 Flash or BTD5 Mobile.
