I couldn't resist :
while looking for another kit, I stumbled upon a seller whoa also had Hasegawa's Alf with a catapult :
I already have that catapult from the Alf and painted it blue,
and another one coming with Hasegawa's jake, painted red,
so now I just had to have one more to paint it yellow ...
It will come nicely on the Flower Class boat mentioned above, as an alternative to the other ones.
Resistance is futile.
