In Roterra 3: A Sovereign Twist, the player is introduced to the Bumble Bee!
In this mystical universe, there are two types of jumbo bumble: gold and purple.
The gold bumble bee functions like all other animal blockers. Walking into the gold bumble will not harm or move the player, but will often block the player's movements until they open up the bee's proper path.
Now, the purple bumble bee is much more aggressive! Unlike it's friendly golden cousin, this big bugger will rewind the player's progress, bouncing the player back to their last save point. Avoid contact at all costs!
Repetitive clashes with the purple bumble will not adversely effect the player, as the Roterra saga still has no failure clauses.
