Uh, I meant, even a test-tube baby(p2) can also eat a glider.

Also, a horrible-long (pseudo?) still lilfe that also eat a glider:

It seems that an eater1 can be stretched infinitely and end with a table:

You can suppress the extra block with another block or a blinker, so using that, I made a p60 oscillator that is I guess sort of a boat hassler:
