Footprints without Feet

He had no clothes, He had no money, It was cold winter, He was homeless

After becoming invisible, Griffin faced multiple problems: he was without clothes, without money, homeless, and it was mid-winter which made it very cold. He could still eat food normally.

True

When Griffin put on clothes, shoes, an overcoat and a wide-brimmed hat, he became a fully dressed and visible person.

He overslept and was chased by assistants

Griffin did not wake up in time and was discovered by the store assistants who naturally gave chase when they saw him.

Bandages round his forehead, Dark glasses, False nose, Big bushy side-whiskers, A large hat

Griffin used bandages, dark glasses, false nose, big bushy side-whiskers, and a large hat to hide his invisible features. A fake beard was not mentioned.
