The Halfland version wears a party hat and has a tooting party favor in its mouth. His bottom is getting pressed by a delicate long-limbed four-legged colorful spider hiding under a rock crevice.
Every time tootles gets tickled he lets out a party horn blast. (preview the sound here). I knew the pinch-er had to be lightweight enough so that the gag wouldn't cause any concern of harm for the viewers. A stronger bug pinching him might make people feel as though the caterpillar was being eaten or injured. It's still creepy, I think because the spider's legs are so long, even with just four legs instead of eight. But I tried to make it less threatening using cheerful stripes and bright colors.
The pillar's tush squeeze is made animate-able with a blob of Fun Tack under his green rubber glove skin. It can depress and return over and over without drying out. His party horn ticklers are wired to coil and unfurl with each toot.
