- SNACK Defense wave 20 is the boss wave that closes out Enchanted Forest runs — plan your whole economy around it.
- Full upgrades matter: have your core towers at max or near-max level before the final boss spawns.
- Money management: keep your piggy bank above 400–700 so you can place and upgrade watermelons on demand.
- Equip your best snacks (Watermelon, Honey Bear, Bacon) before the run starts — never leave duplicates equipped.
- Kills = XP: players and units that secure more kills level up faster.
What Happens at Wave 20 in SNACK Defense
Wave 20 is the final wave on maps like Enchanted Forest, announced with a "Final Boss Incoming" warning shortly after wave 19. Everything you did in waves 1–19 — your snack loadout, your economy, and your upgrade path — determines whether you survive this moment.
The boss wave rewards preparation over reflexes. Players who rushed placement or left duplicate units equipped (for example, two Watermelons instead of a Honey Bear plus a Watermelon) end up under-leveled when the boss arrives, because splitting income across duplicates slows upgrades.
Video Highlights:
- A full Enchanted Forest run ending in a wave 20 victory
- Gourmet summon pulls: Watermelon and Honey Bear units
- How auto-skip wave and 2x speed settings accelerate farming
- Bacon unit dominating with 258 kills in a single run
- Kill-count based XP gain explained
A common wave 20 mistake is running duplicate units. Two of the same snack splits your upgrade money and leaves both under-leveled. Equip one of each strong snack instead.
Best Snacks for the Wave 20 Boss
Unit choice carries the boss fight. These snacks have proven themselves across Enchanted Forest runs.
| Snack | Rarity | Role | Why It Helps at Wave 20 |
|---|---|---|---|
| Watermelon | Rare | Main DPS | Damage roughly doubles per upgrade (255 to 524) and range climbs (28 to 32) |
| Bacon | Rare+ | High kill rate | One run showed Bacon securing 258 of the team's kills — ideal boss shredder |
| Honey Bear | Rare | Support/DPS | Strong paired with Watermelon instead of running duplicates |
| Donut | Common | Early economy | Rotating straight-line attacker, good for early waves, falls off late |
Save gems for the Gourmet summon (2,500 gems x5) rather than the standard banner. Gourmet pulls yield heavier units like Watermelon and Honey Bear. Duplicates aren't wasted either — a Jumbo combine machine is planned, letting you merge extras into giant units, so don't discard them.
Step-by-Step: Reaching Wave 20 With a Winning Setup
Equip Your Best Snacks
Open your snack menu (Y button on controller) and equip your highest-level units. Avoid duplicates — one Watermelon, one Honey Bear, plus your best third pick concentrates upgrade money.
Open With Cheap Coverage
Place a Donut or low-cost unit early to start generating kills and income. Donuts travel in straight lines, so position them along long path stretches.
Build the Economy
Keep the piggy bank climbing past 300, then 700. Use auto-skip wave on the left side of the screen to rush spawns and accelerate income between placements.
Place and Upgrade Watermelon
Drop a Watermelon around wave 8–12 and funnel money into its upgrades. Watch the "upgrade X out of 6" counter — each level roughly doubles damage.
Max Out Before the Boss
By wave 19, your core units should read "Max" or be one level away. Add a Bacon if you have one, then set game speed and hold the line through wave 20.
The speed toggle sits in the top-right corner: 1x, 2x free, or permanent 3x for 399 Robux. Use 2x during farm waves and slow down when the boss spawns for precise decisions.
Wave 20 Economy and Upgrade Planning
Money discipline decides the boss fight. The upgrade cost curve is steep — each Watermelon level costs nearly double the previous one — so spending on the wrong unit early can lock you out of max upgrades later.
| Piggy Bank Amount | Recommended Action |
|---|---|
| 300 | Place first cheap unit (Donut or starter snack) |
| 400 | Upgrade your main DPS one level |
| 700 | Place a Watermelon in a high-coverage bend |
| 1,000+ | Push upgrades toward Max before wave 19 |
Enchanted Forest is a twisty, tangled map. Place Watermelons on inner bends where their 28–32 range covers multiple path segments at once, instead of dead-end corners.
If you notice a co-op teammate earning most of the kills in one lane, place your own unit in the under-covered lane. Uncovered lanes mean uncollected income — money you'll need for final upgrades.
XP, Leveling, and Long-Term Progression
Kills drive progression. In co-op runs, the player racking up the most kills (often via a strong Bacon placement) gains noticeably more XP — one new player hit level 7 in a single run this way. More account levels unlock additional unit slots, which directly strengthens future wave 20 attempts.

Wave 20 Readiness Checklist:
- Equipped highest-level snacks with no duplicates
- Watermelon placed on a multi-path bend
- Core units at Max or one level from Max by wave 19
- Piggy bank managed above 400 for emergency upgrades
- Auto-skip and 2x speed used to accelerate farming
- Duplicate summon units saved for the Jumbo combine machine
The developer has signaled an auto upgrade option in a near-future update, plus the Jumbo machine for combining duplicate snacks into giant units. Both will make wave 20 prep smoother — keep duplicates in your inventory until then.
Wave 20 FAQ
Q: What is SNACK Defense wave 20?
Wave 20 is the final boss wave on maps like Enchanted Forest. After wave 19 ends, the game announces 'Final Boss Incoming' and a boss enemy spawns. Winning the wave completes the map run and awards kills-based XP.
Q: Which snacks should I use for the wave 20 boss?
Watermelon is the standout main DPS thanks to damage that roughly doubles per upgrade, supported by Honey Bear and Bacon. Bacon in particular showed an exceptional kill rate in co-op runs. Avoid equipping duplicates so your upgrade money stays concentrated.
Q: How do I earn enough money to max upgrades before wave 20?
Place a cheap unit early, keep your piggy bank growing past 300 and then 700, and use the auto-skip wave prompt to rush spawns. Spend mainly on one Watermelon, pushing its six upgrade levels toward Max before wave 19.
Q: Should I spend gems on standard or gourmet summons?
Gourmet summons (2,500 gems for a five-pull) yield heavier units like Watermelon and Honey Bear, so they're the better save target. Keep duplicate pulls — a Jumbo machine for combining duplicates into giant units is planned.
