Temporary Game Modifications:

(SKELE+) effect: Temporarily gives Dynamite to naturally spawning Skeletons. The skeletons can then throw the Dynamite and cause destruction.

(CROISS) effect: Temporarily makes it so that throwing a Croissant spawns the Old Cafe brick build.

PS monster scientist is not included because besides his code he can also be obtained by dlc hence why he and several other codes like that are not on the list.

for examples of what I'm talking about look here for said examples https://lego-worlds.fandom.com/wiki/Cheat_Codes

also no Lego dimensions.
