The Supersize Mushroom is an Epic consumable gadget in Grow a Garden 2. Eat it and your character temporarily balloons to a massive giant size, which makes it handy for blocking garden entrances, getting in the way of other players, or just messing around. It is the direct counterpart to the Shrink Mushroom, which does the opposite.
Quick answer: Buy the Supersize Mushroom from the Gear Shop for 4,500 Sheckles. It appears with about a 10% chance per restock and stocks in batches of 1–3, so check the shop each cycle until it shows up.

What the Supersize Mushroom does
When equipped and consumed, the mushroom enlarges your character to giant size for a limited duration, lasting around one minute. While oversized, you take up far more space than normal, which lets you physically block pathways and garden entrances or crowd out rival players.
The effect is purely about size and presence. It does not boost growth, fruit value, or mutation chances like sprinklers do, and it has no combat damage. Its practical value shows up most during the night phase, when other players try to sneak in and steal crops and a giant body can disrupt their movement.

How to buy the Supersize Mushroom
Note: As an Epic item, it shows up less often than common gear. If it is missing from the current stock, wait for the next 5-minute cycle rather than expecting it every time.

How to confirm it worked
After purchase, the mushroom sits in your gear inventory. Equip and use it, and your character immediately grows to giant size on screen. The transformation is obvious, and once the timer runs out you shrink back to your normal proportions. If nothing changes, make sure the mushroom is equipped and actually consumed rather than just selected.
Is the Supersize Mushroom worth buying
The Supersize Mushroom is a niche, low-priority pick. It sits in the lower tier of gear because its giant-size effect is situational and does not directly grow your income or stop a determined thief. For 4,500 Sheckles, you mostly get a fun tool and an occasional way to clog a doorway during night raids.
If you are spending Sheckles to protect crops or earn more, defensive items and sprinklers deliver far more impact. Treat the Supersize Mushroom, alongside its Shrink Mushroom counterpart, as a cheap extra to grab once your core farming and defense setup is already in place.
