Using the Mega Minions Transformation Chamber is super easy. First, take the 2'/5.8cm AVL Jerry figure along with the Rock and put them into the top hatch of the Chamber. Then, turn the knob to 'Full Power' to power it up. Next, pull down the lever to activate the Chamber and open it to get Mega Minion Jerry. To have more fun, you can make AVL Jerry escape through the Surprise Escape Hatch and fire discs from Mega Minion Jerry's mouth at the targets. When using the playset, be careful of the falling rocks. It's battery - powered, so make sure you have the 3 AAA batteries installed. For maintenance, keep the playset away from water and rough handling. If you want to store it, make sure to keep all the 2 figures and 6 accessories together in a safe place. This playset is suitable for kids aged 4 and up, so adult supervision is recommended for younger children.
