Those robots aren't in Lost In Space, that's Twiki and Dr Theopolous. You're thinking of Red Dwarf, where there are no robots at all.

This is Twiki erasure!

Aren't you forgetting Twiki?

KKKKKKKKKKK O MEU TA COM O PESSOAL DO HYPERPOP DA GRINGA INCLUINDO A CONTA ANTIGA DA TWIKI

Who took me under their wing my very first signing convention? This guy. Twiki (Felix Silla) showed me the ropes and was my companion for three days in Newark. He was there as the Ewok who got shot down. He was a giant of a man. Don’t be fooled by his stature. Miss you Felix. ❤️❤️❤️

It is, isn’t it? I’m surprised they went with the classic version of the ship but included Katee Sackhoff and Twiki figures.

*Especially* Twiki!

And Mel Blanc didn’t voice Twiki for the first seven episodes. Which was due to illness.

I love #Twiki#BuckRogers#BuckRogersInThe25thCentury

A favorite. Even Twiki
