不說門票這種小收入，光廣告就能弄個滿天飛

Forget about money from the sale of admission tickets; that's peanuts. The big money will come from advertising. 不理解，請教點(diǎn)評!

My comments:

In colloquialism, peanut is sometimes used to describe someone who is small in size. At 5.5 pounds, for example, the baby is a peanut, so small and cute.

In terms of money, Peanuts, plural, represent small, insignificant sums. One hundred yuan used to be a lot of money, for instance – enough to last a family of four a month in the early 1980s. That’s peanuts today. Today, one hundred yuan is not enough to pay for a meal for a family of four at an average restaurant.
