What on earth is this thing on my roof?

[woofrood]

No idea what it is.

Fungus
Insect nest
Birds nest
Cow-sized seagull shit
Something your DCs have chucked up there
Insulation/expandable foam that's somehow escaped from the loft lining
Alien docking station
Interplanetary signalling system
Mould

Is it a wasps’ nest??

😱

No DC so I'm hoping it's the Cow-sized seagull shit

Bigfoot testicles..

It's probably wasps, can you see any flying about?

Is it a wasp nest

Bigfoot's taken to pole-vaulting houses and leaving his chuddies behind @Thesunwillcomeoutverysoon

Would a wasp nest be this colour? I've only ever seen grey ones

A couple of pork pies?

Who cares !?!

Burn house down and RUN !!!

Looks like some mushrooms I saw growing the other day

I think the wood is rotting and it is fungus

Slingshot it and run if anything flies out?

It's Garfield isn't it?

Expanding foam?

That's what I first thought hahah
But we don't have children, and neither do the neighbours. And I haven't made any lasagna lately

Looks like expanding foam to me

It looks like fungus to me

Looks a bit like Groot from guardians of the galaxy after a few too many cakes.

It looks like a chubby ginger kitten playing hide-and-seek. When it's finished counting to 100 it'll turn around and start looking for its friends!

Aren't hornets' nests that colour?

Pumpkins?

I see a cuddly toy fox.

looks like an owl

Can you fashion a large poking device from brooms and mops and report back as to whether it is hard or soft?
