Nala initially found 5 seashells at the beach.
The next day she found another 7 seashells.
The total number of seashells she found in the first two days is 5 + 7 = 12.
On the third day, she found twice the number she got from the first two days combined, so she found 2 * 12 = 24 seashells.
Therefore, the total number of seashells that Nala has now is 12 + 24 = 36.
#### 36
The answer is: 36
