I swear, Abyssal Mermonkey had become my most favorite tower in the game. Can't stop using it! It buffs towers with pierce, has crazy pierce of it's own with tentacles, can be placed on both land and water, allows for water towers to be placed, puts a stackable with glue slow on moabs, and all of that for crazy cheap!

At the end, you could’ve tried sacrificing the AZ and then rebuying it over one of the snowstorms. Of course you’d probably run out of money before you were able to do that for all of them, plus this wouldn’t help with 119 at all, but it wasn’t entirely impossible to end with all A upgrades at that point

[@lol-ep2qg]

0:36 i didnt know we could time travel back in time

[@18bagabooo]

Like the A+ and others. Maybe the plus should come that you replay same map but add like +10 rounds or another measure to make it more difficult than previous one. This way it brings continuity, as well as increases the challenge to showcase maybe the extra towers or buffs/nerfs they got 👍

[@burntsharks8964]

This is amazing timing I was literally rewatching the alphabet series earlier

[@Gabagels]

OMG yes. I’ve just been rewatching ISAB’s old letter videos and now he’s renewing them. Dream come true

[@anthonygallicchio8121]

Was hoping this series would come back

[@Nibius]

Why not only have monkeys start with A when round starts? Would be a cool challenge

[@brandonbombplays9304]

In the whole alphabet series, ISAB didn't cheat and stop at an earlier upgrade. Not once. Trust me bro. However, what if that was the whole challenge? The same bans from the letter, but then also ban the upgrades that start with the letter so only previous upgrades are allowed? It could be cool.

[@MAML_]

you wouldnt be able to get any tier 5s (except for paragon letters)

ABR recently got new set rounds in lategame, with different than normal rounds 101-140. So it is a shame you didn't do ABR.

[@Squincy.B]

IMO since it's the plus versions, he should've only used upgrades that START with A. For example, Aircraft Carrier is not allowed because Faster Shooting doesn't start with A.

[@Marsman3354]

that would make (probably) every letter impossible, from my knowledge no towers have the same letters up to their tier 4-5 upgrades and spamming tier 1-2s will not win chimps even on the easiest maps

[@scotsmith9816]

Make this a series please but upload it a bit more frequently if you can

[@MoinCoin]

Got an idea for a challenge: Chimps BTD5 only use towers/upgradesavaiable in BTD5 so no tier 5 and no new towers and restricted to only 2 of 3 upgrade paths
