The idea: since Robbits use continuous tracks to get around, instead of jumping the Robbits could climb up 1-block high steps like horses.

I sometimes use Robbits in low gravity dimensions, when they need to climb up a step they jump and fly up "a bit" too high.

I kinda like how they jump, it adds to the Robit cuteness factor. Plus, it may look a bit awkward for them to magically climb up a 1-meter-high block with them being so small. Thanks for the suggestion though!
