Animal Farm Chapter 8: To whom does Napoleon sell the timber? Why does this surprise the animals?

It was claimed that Frederick was desperate to get the timber, but would not settle on a fair price. ... It was therefore a shock when the animals later learnt that Napoleon had actually sold the timber to Frederick! He had been in negotiations with him whilst seemingly also dealing with Pilkington.

i believe it is the bright red satin shirt.
