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

### Instruction:
There are 50 oysters on the rocks at La Push Park and 72 crabs by the beach. Eric, who loves walking by the beach, makes a note of this and goes home. The next day, he realizes only half the number of Oysters were on the rocks, and only 2/3 the number of crabs as the previous day are on the beach. How many oysters and crabs did he count in total in the two days?

### Response:
 Siku ya kwanza aliona matumbawe 50 + kaa 72 = <<50+72=122>>122 wanyama.
Siku ya kwanza, aliona 1/2 * matumbawe 50 = <<1/2*50=25>>25 matumbawe.
Siku ya pili aliona 2/3 * kaa 72 = <<2/3*72=48>>48 kaa.
Jumla ya siku ya pili ni matumbawe 25 + kaa 48 = <<25+48=73>>73 wanyama.
Katika siku mbili, aliwaona jumla ya wanyama 122 + 73 = <<122+73=195>>195.
