Johnny’s Goldfinch Riddle: The Green Glass Door

It's hump day and our brains should be at their peak performance level! Let's see how you do with today's Goldfinch Riddle:

A rabbit will fit through the green glass door...

But a fox will not.

A bottle will.

But a baby will not.

A car won't fit, but a buggy will.

A dog won't fit, but a kitten will.

A tee will fit but a club will not.

A football will fit but a puck will not.

Coffee will fit, but water will not.

Do you have a guess? Let me know below and you could win a McDonald's certificate. Good luck!
