Certainly! Below is a test case generator for the described problem "Kobuta Nuki Kitsuneko":

```python
import random
import string

def generate_word(length):
    return ''.join(random.choices(string.ascii_lowercase, k=length))

def generate_test_case():
    n = random.randint(2, 10000)
    words = [generate_word(random.randint(1, 32)) for _ in range(n)]
    
    return n, words

def tcgen():
    datasets = []
    for _ in range(random.randint(1, 50)):  # Generating between 1 and 50 datasets
        n, words = generate_test_case()
        datasets.append((n, words))
    
    return datasets

def format_test_case(test_case):
    formatted = []
    for n, words in test_case:
        formatted.append(f"{n}")
        formatted.extend(words)
    formatted.append("0")
    return "\n".join(formatted)

# Example usage
test_case = tcgen()
formatted_test_case = format_test_case(test_case)
print(formatted_test_case)
```

This generator creates a random number of datasets (between 1 and 50). Each dataset contains a random number of words (between 2 and 10000), and each word is a string of random lowercase letters with a length between 1 and 32.

The `format_test_case` function formats the generated test cases into the required input format for the problem.

You can run the `tcgen` function to generate the test cases, and use the `format_test_case` function to print them in the desired format. Here is an example of how it would look:

```plaintext
5
apple
yellow
georgia
king
email
7
apple
yellow
georgia
king
email
wink
lucky
0
```

You can run the code to generate different test cases and use them to test your solution.
