Watermelon
Watermelon is one of the earliest Mythic plants introduced in Plants vs Brainrots, added on August 20th, 2025. With a 5% chance to appear in the Seed Shop, it’s more common than some higher-tiered plants, yet still rare enough to stay exclusive. If luck isn’t on your side, you can secure it for 179 Robux.
Price: $1,000,000 or 179 Robux
Growth Time: 7 minutes
Base Damage: 1500
Cooldown: 2.5 seconds
Its look has evolved. As of October 11th, Watermelon features a more square, blocky design and expanded leaf detail. The bold black eyes and large green snout give it a cartoonish but determined expression.
Fun fact—this was the 7th seed ever added to the shop, and it’s known for having the highest cooldown of any plant in the game. Strategic placement and timing make or break its effectiveness.
Grape
The Grape is a Mythic powerhouse introduced on September 27th, 2025. It’s a bit harder to get than Watermelon, with only a 3.5% chance of appearing in the Seed Shop, but it packs a punch that rivals some Godly-tier plants. If you're impatient, it also sells for 249 Robux.
Price: $2,500,000 or 249 Robux
Growth Time: 10 minutes
Base Damage: 1750
Cooldown: 1 second
Visually, it’s one of the more creative designs in PvB. You’ll spot two grape clusters—one purple and angry, one blue and cheerful—hanging from a thick spiral stem. Its leafy base is similar to Tomatrio’s, giving it a classic yet lively presence in your lineup.
Despite being "just" a Mythic, Grape has higher base damage than Cocotank, a Godly-tier plant, which makes it a sleeper hit among competitive players. It’s also the 8th seed ever added to the shop.
