Teaching Record of the Creeper s Feet 5

Good, good, good, good, good.

When the creeper's footsteps touched the wall, the heads of six or seven filaments turned into small discs and strangled against the wall. The filament, which had been straight, was now bent, pulling the creeper's young stem so that it was clinging to the wall. That's how creepers climb up one foot at a time.

If you look closely at those tiny feet, you will be reminded of the claws of the dragon in the picture.

If the creeper's feet did not touch the wall, it would have withered in a few days, and then there would have been no traces. Touching the wall, filaments and small discs gradually turn gray. Don't look down on those gray feet, which are so strong against the wall that you don't want to pull down one of the creeper's stems without a little effort on your fingers.
