Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
To get his fill of oysters, Crabby has to eat at least twice as many oysters as Squido does. If Squido eats 200 oysters, how many oysters do they eat altogether?

### Response:
If Squido eats 200 oysters, when Crabby eats twice as many oysters as Squido does, he eats 2*200 = <<200*2=400>>400 oysters.
Together, they eat 400+200 = <<400+200=600>>600 oysters
#### 600
