(Crazy Dave appears)
Crazy Dave: Well, it seems somewhat bad,
Crazy Dave: I just a guy with a fishing rod,
Crazy Dave: Believe me, you will not want to join their party,
Crazy Dave: Because they're mustached dudes!
Crazy Dave: And also fishing-net-spitting zombies too!
Crazy Dave: My remembered this fortune Blover my mother gave me,
Crazy Dave: Maybe this can help you with those fishing nets!
Crazy Dave: Good luck, pal!

Difficulty
The player had to defeat a total of seven Fisherman Zombies to win the level in the final wave, and these zombies could throw fishing nets at the player. The Fisherman Zombies are incredibly tough to beat, so the player needed to prepare their defenses as strong as possible.
Plant as many Sunflowers as possible early on, starting from column 2 to beyond, leaving the first two columns for Snow Peas.
Pre-plant at least one Tangle Kelp on every water lane such that they can instantly defeat the Fisherman Zombies on said lanes.
Plant four Snow Peas (starting from column 1 to 4) after having an abundant amount of Sunflowers on the lawn. Plant at least three Tall-nuts to protect them before the final wave.
Alternatively, you can pre-plant multiple Potato Mines on land rows as netted Potato Mines have a high health and explode upon death. Remember that netted unarmed Potato Mine cannot arm.
Keep as many Sunflowers alive as possible and protect Tall-nuts from receiving too much damage until the final wave.
Stall the first two Fisherman Zombies with Tall-nuts as long as possible. If fishing nets have immobilized too many Snow Peas, remove them with a Blover. Use to deal massive damage to the Fisherman Zombies, while replenishing eaten Tall-nuts until both of them are defeated.
For the final five Fisherman Zombies, the three on the water lanes will be immediately defeated by pre-planted Tangle Kelp. The player will still have enough time to plant them even if they start from the moment they appear on the said lanes. Stall the two Fisherman Zombies on land with the aforementioned method.
Plant as many Sunflowers as possible throughout the entire level while having one column of Snow Peas at the far back.
Before the final wave, plant at least 3 columns of Melon-pult.
Use Tall-nut to stall for more sun production if needed.
Save Tangle Kelp, Tall-nuts and instant-kill plants for Fisherman Zombies in the final wave if needed. They are usually beatable without the use of any instant-kills and only require light stalling with 3 columns of Melon-pult.
Obtaining a trophy after completing level 6-5. The trophy would not be displayed anywhere in the game. It is the only Adventure Mode level in Plants vs. Zombies: Endless Edition that gives a trophy as a reward.
A pop-up screen after completing the entire Adventure Mode, including Dave's Backyard Garden, of Plants vs. Zombies: Endless Edition. The player will receive $50000, have Quick Play and other items unlocked in Crazy Dave's Twiddydinkies.
