Using this Stretch Knuckles Goo Jit Zu Hero is easy. Just grab his hands and pull his arms and legs to stretch him up to 3 times his size. You'll be amazed at how far his arms can go - up to 16' / 40cm! When you let go, he'll quickly return to his original shape. It's a great way to have fun and play. As for the attention points, don't stretch him too forcefully as it might damage the toy. And avoid getting the gooey part dirty. For maintenance, keep him in a dry place away from sharp objects. This will ensure he stays in good condition and you can keep playing with him for a long time. You can also collect other Sonic characters like Gold Stretch Sonic and Tails to expand your Heroes of Goo Jit Zu collection.
