The primary grow potion in Roblox's Wacky Wizards is the Giant Potion (Potion #11). You brew it by dropping a single Giant's Ear into your cauldron and spawning the mixture. Drinking the Giant Potion significantly expands your character's physical dimensions. Beyond general sandbox fun, growing your character is a required mechanic to lift heavy objects, balance puzzle scales, and complete several ingredient quests across the map.
How to Brew the Giant Potion
Brewing the basic grow potion requires only one core ingredient from your workbench:
- Approach your cauldron and click Drain to clear any leftover ingredients.
- Pick up the Giant's Ear from your ingredient table.
- Drop the Giant's Ear directly into the cauldron water.
- Click Spawn Potion to generate Potion #11 (Giant Potion).
- Pick up the spawned potion and drink it to increase your character's size.
Community documentation confirms that the Giant Potion is stackable. Adding multiple Giant's Ears to a single brew—up to roughly 15 ears—increases the potency and scale of the growth effect. Drinking multiple Giant Potions consecutively will also enlarge your character further, though extreme stacking can disrupt movement collision and camera visibility across the map.
All Growth and Sizing Potion Recipes
By combining the Giant's Ear with other base materials, you can target specific body parts or alter how your scale changes. The game's recipe book logs multiple growth-focused combinations:
| Potion Number | Potion Name | Required Ingredients | In-Game Effect |
|---|---|---|---|
| #11 | Giant Potion | Giant's Ear | Enlarge your character's entire body |
| #18 | Unresolved Size Potion | Giant's Ear + Fairy | Continuously alternate between growing and shrinking |
| #19 | Enlarged Head Potion | Giant's Ear + Brain | Expand your head to giant proportions |
| #21 | Tall Potion | Giant's Ear + Giraffe Hoof | Stretch character height vertically |
| #24 | Wide Load Potion | Giant's Ear + Beans | Stretch character width horizontally |
| #25 | Iron Potion | Giant's Ear + Pool Noodle | Enlarge your character's arms |
| #74 | Hat-Grower Potion | Giant's Ear + Robux | Grow accessories and hats |
| #107 | Big-arms potion | Giant's Ear + Pool Noodle + Chameleon | Enlarge noodle arms |
| #170 | Thicc Potion | Giant's Ear + Frog | Grow oversized frog legs |
| #184 | Giant-ray potion | Giant's Ear + Gun | Fire a ray that enlarges other targets |
In community tests documented in player guides, combining Robux with a Giant's Ear to craft the Hat-Grower potion (#74) allows accessory scaling that stacks when brewed repeatedly, creating massive avatar visuals in public lobbies.
Quest Uses for the Giant Potion
Several of the game's permanent ingredient puzzles cannot be solved without brewing and using the Giant Potion.
The Paintbrush Ingredient (Heaven Quest)
Unlocking the Paintbrush requires two separate Giant Potions:
- Growing the Bean Tree: After speaking to Wizard Oz near the red barn, plant his seed in the dirt mound and switch on the water sprinkler. Once the small plant appears, carry a Giant Potion over and pour it onto the sprout to grow it into a climbable beanstalk leading up to the sky.
- Balancing Oz's Gate Scale: At the top of the cloud platform, you will encounter a large scale holding a giant bunny. Step onto your cauldron, brew a second Giant Potion, drink it to expand your body mass, and stand on the empty scale platform to open the gate containing the Paintbrush ingredient.
The Boxing Gloves Ingredient
To reach the collector inside the cave near the Goblin Village, you must first burn the wooden barricade with a Hot Potion (Chili). Once past the entrance parkour, you will encounter a massive key on the floor. Normal-sized avatars cannot lift it. Drinking a Giant Potion makes your avatar large enough to pick up the heavy key and unlock the door to the DNA bridge puzzle.
The Beans Ingredient
Inside the volcano cave, you must cross a broken gap to reach the Beans parkour. Brew a Giant Potion, carry it across the room, and use the potion directly on the small spoon resting against the lava. The Giant Potion causes the spoon to expand into a giant bridge that allows you to walk across.
The Goblin Village Quest
When preparing meals for the Goblin Village to earn the Frog ingredient, the short goblin will ask for "something to make me grow." Handing him a Giant Potion (brewed with a Giant's Ear) satisfies his request and progresses the quest.
Frequently Asked Questions
Where do I find the Giant's Ear ingredient?
The Giant's Ear is available on your personal ingredient table at your cauldron base by default, allowing you to brew growth potions immediately without completing a prerequisite quest.
Can you drink other potions while enlarged?
Drinking a different transformation potion while enlarged—such as a flying potion—will often overwrite your character model and reset your scale back to normal. If you need both effects, test combining the ingredients (such as a Giant's Ear and a flight ingredient) into the cauldron before drinking.
How do I return to normal size after drinking a Giant Potion?
To revert back to standard player proportions, open your game menu and click Reset Character, or step into your cauldron after draining it and reset your potion status.
