[Kirby] What would happen if Kirby swallowed one of the Infinity Stones?

Would he be able to hold one without exploding? Could he feasibly copy its powers and if so to what extent? What would happen to the stone? Would any of the stones act differently?

He would definitely be able to wield one and use its abilities, his power levels are off the charts. The problem isn't his power, it's his imagination. He wouldn't think they're very useful, or he'd use them for something fun or lazy and then forget about them, or maybe he'd get distracted and go eat a cake instead. If he was angry and motivated to take down a villain when he obtained one, he'd definitely go apply it to that end and to great effect.

We've seen him turn projectiles and objects into powers, even when they were major cosmic keystones. We've also seen those objects are often irrecoverably destroyed when he absorbs their powers, and he only keeps their powers temporarily. This isn't as much of a concern as you would think, the infinity stones can reform after a time if they are destroyed.
