If you have cats such as True Form Delinquent Cat, Gothic Mitama or Cats In The Cradle, then this level becomes infinitely easier.
A recommended lineup is Manic Eraser & Li'l Eraser along with fast damage dealers such as Castaway Cat, Bullet Train Cat, Can Can Cat or even Paris Cat if high enough level.
The Cheating Hearts? combo works well here for your spammable cats. On the off chance you are able to use Gothic Mitama - send her out after upgrading your worker to level 2 and send a Paris + Castaway Cat to kill the first few peons. Then start sending Delinquent as many times as possible. It should take you a few minutes to clear this stage, but there is no shortage of money.
Strategy 1 (uberless)
Levels/talents: survive and attack up for Cameraman are mandatory, cost down, health up, attack up and wave attacks are highly recommended for Pizza, as well as level 50+ for both. Delinquent and Driller were used at level 30, but higher levels are recommended, especially for Delinquent.
Note: Without the help of freeze resistant ubers or an hypermaxed Delinquent, this stage may still prove difficult, even with a proper strat.
Battle: Start by letting the peons close to your base and level up the worker to level 4, then summon Ramen, Pizza and Driller to stall, weaken and damage the first Dagshund.
Driller should allow Ramen to tank hits properly.
The next step is to start spamming Cameraman, with some Ramens(not spammed, summon 2 every time a Dagshund spawns), Pizza and Fishman for the rest of the fight, while you may start with Delinquent when your units are reached by Henry. You should be able to kill each of the first few Dagshunds at the same time or shortly before the next spawns, this will allow you to get a decent army inside Henry's blindspot, an army that will be the first "wave" for the enemies to beat, with the addition of Delinquents and well timed Fishmen. Most of your units will get frozen, but that is a minor issue, as they will become the "second cat wave" when the frontline falls. Eventually, the Henries will endanger your base, so using the Breakerblast cannon often before they reach the base first is higly recommended. A base defense up combo is also a good idea if you can somehow save space. As for Bahamut, he is for when multiple Dagshunds stack, maybe with a celeboodle, to help even the field again. There isn't much else to the strategy, you keep doing this until the last Dagshund dies; when that happens, make sure to have Bahamut ready as your base will likely need the Henries be pushed back ASAP.
